This two week intensive course is intended for students interested in learning the principles and methods of probability and statistics needed for analyzing, modelling and interpreting data. Basic (high-school) familiarity with statistical concepts is assumed. The topics covered include probability distributions, Bayesian reasoning, hypothesis testing, maximum likelihood, linear regression, monte carlo methods, etc. Mathematical proofs and derivations will be kept to a minimum (although matrix operations are very important) and greater emphasis will be placed on how to practically apply statistical tools to help you interpret real data. The course will be taught in the R programming environment (no prior knowledge of R is assumed). The course is recommended for students that have already completed the first two semesters. (If you are having trouble registering for this course on heiCo, email the lecturer directly with yout name and matriculation number to be added manually.)

Motivation Entscheidende Experimente legten die Grundlagen der Quantenphysik und geben weiterhin Impulse für ihre Weiterentwicklung. Intensive Forschung auf dem Gebiet der Quantenstruktur und -dynamik ermöglicht es immer noch, die Grenzen der bekannten Physik durch überschaubare Experimente zu erweitern. Die in der modernen Atomphysik realisierbare Präparation exquisit isolierter Quantensysteme sowie die unübertroffene Genauigkeit ihrer Messmethoden erlauben auch die Suche nach Physik jenseits der Standardmodelle; daraus entstandene Quantensensoren sind zu unverzichtbaren Werkzeugen der Physik und der allgemeinen Wissenschaft geworden. Das Seminar soll einen Überblick über Präzisionsexperimente mit atomaren Systemen und ihre aktuellen Anwendungen auf fundamentale Fragen der Physik geben. Beispiele für mögliche Themen sind: -Wasserstoffatom: Bohrmodel, Lamb-Verschiebung, Protonenradius -Atomstrahlen, Atomfallen, Laserkühlung -Atomuhren, Frequenzmetrologie und Suche nach neuer Physik -Elektronen, Protonen und Antimaterie in Ionen- und Atomfallen -Tests der Quantenelektrodynamik mit Penningfallen -Röntgenspektroskopie von astrophysikalischen Plasmen mit hochgeladenen Ionen -Beschleuniger und Speicherringe in der Atom- und Molekülphysik -Studien der Paritätsverletzung in Kernzerfällen und in atomaren Systemen -Ionenfallen: Quantisierung der Bewegung, Verschränkung, quantum computing -Quantentests zu Naturkonstanten, Lorentzinvarianz, Dunkler Materie und neuen Teilchen Bose--Einstein-Kondensation und Quantenstatistik -Ultrakurzpulslaser und Quantendynamik: von der Nano- zur Femtosekunden-Zeitskala -Erzeugung von hohen Harmonischen und Attosekundenpulsen -Zeitaufgelöste Messung der Elektronendynamik in Atomen und Molekülen -Physik von Freie-Elektronen-Lasern Erster Seminartermin: 28.10.2025 Zeit: wöchentlich, Di. 16:00 bis 18:00; Ort: INF 227 / Übungsraum (622703402) Dozenten: José R. Crespo López-Urrutia Anmerkungen - Die Seminarvorträge (Deutsch oder Englisch) werden in der Regel 35 Minuten plus Diskussion dauern. - Eine regelmäßige Teilnahme (>80%) und die Abhaltung eines Vortrags sind Voraussetzung für das erfolgreiche Bestehen des Kurses (PSEM, 2LP). - Ein zusätzlicher LP (UKS2) wird für die Vorbereitung einer schriftlichen Ausarbeitung des Vortrags mit Folien und inhaltlichen Angaben vergeben werden. - Die Benotung der Lehrveranstaltung wird sowohl die Vortragsvorbereitung und -durchführung als auch die aktive Teilnahme an den Diskussionen berücksichtigen. - Vier Wochen vor dem jeweiligen Termin wird vom Betreuer (crespojr@mpi-hd.mpg.de) die für die Vorbereitung des Vortrags notwendige Literatur geschickt.

In this astrophysics lecture we cover the theoretical concepts of how planets and planetary systems are thought to form. This includes the planets in our solar system as well as exoplanets. The journey starts with the formation of a star, surrounded by a disk of gas and cosmic dust: the protoplanetary disk. This disk is the environment in which (and contains the matter from which) planets form. We will therefore discuss in quite some depth the structure, dynamics, thermodynamics and chemistry of these disks, including radiative transfer, hydrodynamics, magnetohydrodynamics, etc. And we will discuss the wealth of observations of these disks that have been obtained, in particular in the last decade, with the VLT and Subaru telescopes, with ALMA, and with several space-borne telescopes such as JWST. We will then move on to discuss the richness of physical phenomena that underpin the long journey from micrometer-sized dust (=rock) particles all the way to many-thousand kilometer sized planets. These include, among other things: gas turbulence, dust particle drift, coagulation and fragmentation of dust aggregates, formation of planetesimals through streaming instability, restricted three-body problem, dynamical friction, pebble accretion, planetary migration, planetary collisions, N-body dynamics, gas accretion, (pebble-)isolation mass, planetary interiors, equations of state at high pressures and temperatures, phase diagrams of rocks, magma oceans, clues from the Solar system (meteoritic evidence, planetary orbits, etc), and many more.

In this seminar, we will cover YOUR topic of interest in physics. If you still want to find and/or develop your passion for a specific science area, I can provide some stimulus in terms of topics to choose from. However, I highly appreciate if you already know your topic of choice and introduce it to your fellow students and myself, and we can all discuss it together. This seminar, in general, aims at current and foundational experimental and theoretical advances of physics. The idea is to prepare presentations and to discuss topics of interest in physics, such as landmark historical or recent experiments but also experimental or numerical methods (e.g. computational physics), depending on interest and initiative of you as participants. Each seminar talk, given by a student, should introduce into the fundamentals of the chosen topic in a manner understandable to any general physics student of your own academic age, and present one or two noteworthy recent results or achievements in this field. A key goal is to explore and develop your own scientific curiosity and passion for physics questions of interest to you, concepts, necessary methodology and past, current and potential future research. It thus requires from you as participants the openness towards these goals, readiness for lively discussions, creative new ways of sharing knowledge, as well as independence in searching for, organizing, presenting novel information with your fellow student participants of this seminar series and engaging them in (constructive as well as critical) discussions. Looking forward to learning together with you. Our first meeting will take place on 17 October 2025, where we will assign the dates for your presentations. We will then meet at this time in the same place for the following seminar meetings as well. Webpage Seminar: tbd Webpage Pfeifer Division: https://www.mpi-hd.mpg.de/pfeifer/

Die folgende Liste der Themen ist als Anhalt gedacht: • Modell eines Tornados: Drehimpulserhaltung, Unterdruck, herleiten wie groß die Windgeschwindigkeit und Unterdruck sind. • Magnetfeld Erde: Ausrechnen welche Sonnenteilchen/Kosmische Strahlen abgelenkt werden. Wie gefährlich wäre der Sonnenwind (vor allem coronal mass ejections) für Astronauten? • Autounfall: Ausrechnen bei welcher Geschwindigkeit ein Airbag noch Sinn macht bei einem Frontal-Zusammenstoß. • Alternative Energie: Ausrechnen wie viel Windmühlen und wie viel m^2 Sonnenzellen man braucht, damit Deutschland 100 Prozent auf neuerbare Energiequellen umgeschaltet ist. • Raketengleichung: Herleitung und Anwendung. Warum war die Saturn V Rakete so riesig, obwohl man mit einem Mini-Lunar Module von der Mond wegkommen konnte? • Flugzeugflügel: wieso können Flugzeuge fliegen? • Tsunamis: Shallow water equation für die Analyse von Tsunamis. Warum (und unter welchen Umständen) sind Tsunamis so gewaltig? • Blitze (Gewitter): Wie funktionieren sie ungefähr, und wie kann man die Lautstärke berechnen. Vielleicht eine Abschätzung davon, wie viel Hagelkörner man braucht um genügend Ladungs-Separation zu machen um überhaupt Blitze zu erzeugen. • GPS-Navigation: Spezielle und allgemein-Relativistische Effekte.

Astronomical and cosmological observations require the existence of dark matter in our universe. Today, Dark Matter is generally thought to have particle nature, where the dark matter particles have relatively long lifetimes, interact gravitationally and, possibly, also via the weak interaction. In the Standard Model of particle physics, only neutrinos have the correct properties, but, due to their small mass, neutrinos can only account for a small fraction of the observed Dark Matter in our universe. In extended versions of the standard model sterile neutrinos, in particular keV-sterile neutrinos can contribute as warm dark matter candidates. Light supersymmetric particles are an example for weakly interacting massive particles (WIMPs) which are candidates for cold darm matter. Other viable dark matter candidates are axions, which have been introduced to solve the strong CP-problem of QCD, or axion-like particles. The seminar will address the astrophysical and cosmological evidences which led to the postulation of dark matter. It will discuss the most prominent dark matter candidates and the different direct and indirect methods to search for their existence. Particular emphasis is put on the determination of neutrino masses, the search for sterile neutrinos, WIMPS and axions.

Condensed Matter Theory I: The complexity of 1023 particles interacting with each other in a solid give rise to many emergent phenomena one would not predict from the simple interactions between two electrons. In this lecture we will, starting from simple models and theories work our way into the contemporary theory of many particle physics. The lecture follows for a large part the textbook of Ashcroft and Mermin, with one big difference. The aforementioned text-book is based on a text over 50 years old. During the last decades new methods have emerged, often removing the need to know the full wave-function of the system to answer the problem, by using Green's functions. Whenever possible the later will be used within this lecture. Concepts of many particle systems discused are: The Drude Theory of Metals The Sommerfeld Theory of Metals Electrons in a periodic potential Tight binding Band-structure, Fermi-surface, Density of states, Metals, Insulators, Semiconductors Semiconductor physics Surface states Phonons and disorder Relativistic corrections - spin-orbit coupling Phase transitions and topology Response functions Theoretical / Mathematical tools used will be Second quantization Green's functions (on an independent particle level) Self energy (for surface states and disorder) Levels of theory discussed will be Mean-field theory Hartree-Fock Density functional theory

Motivation: After discussing dynamical systems on the level of ODEs in the last semester, we here will discuss how to transfer the knowledge to PDEs with a focus on pattern formation and solitons. Pattern formation is one of the most fascinating and intriguing phenomena in nature: it takes place in a wide variety of physical, chemical and biological systems and on very different spatial and temporal scales: examples are convection phenomena in geosciences and meteorology, but also patterns occurring in chemical reactions and bacterial colonies. In some circumstances, pattern formation is undesired, for instance the formation of spiral waves leading to cardiac arrhythmias in the heart muscle. In other contexts, pattern formation is even essential for the functioning of a system as in cell division and embryo development. Contents: We will study spatio-temporal behavior, i.e. partial differential equations (PDEs) and discuss the main questions in pattern formation: when will a homogeneous state become structured, i.e. unstable towards a pattern? What are the generic scenarios/types of patterns? When are patterns stable and are they unique? What determines the wavelength / period in time / amplitude of a pattern? A universal description of pattern dynamics exists, i.e. amplitude equations can be derived that are related to the famous Ginzburg-Landau equation (Nobel Prize in Physics 2003, originally derived for superconductivity). Nonlinear waves and solitons (localized waves) will also be discussed. They again occur in many systems, from coupled nonlinear springs to hydrodynamic surface waves and nonlinear optics.

This advanced theory lecture builds on the statistical physics course (MKTP1) and introduces paradigmatic models of statistical physics and their critical properties near phase transitions. In particular, we shall discuss the Heisenberg and O(N) vector models, the nonlinear sigma model, the XY model, the Sine-Gordon model, and the spherical model. By computing their critical behavior, one can understand the phase transitions in many different systems in statistical physics, condensed matter physics and beyond, which belong to the same universality classes. We will use field theoretic methods and introduce renormalization, epsilon expansion, and duality transformation. Contents: 1. Landau theory and O(N) vector model 2. Renormalization group and universality 3. Nonlinear sigma model and epsilon expansion 4. Topological excitations in the XY and Sine-Gordon models and the Berezinskii-Kosterlitz-Thouless transition 5. Spherical model and quantum phase transitions 6. Disordered systems 7. Random walks 8. Critical dynamics

We will give an introduction to classical non-equilibrium physics, both on the macroscopic (thermodynamic) and the microscopic (kinetic) level. We will start by generalizing equilibrium thermodynamics to spatial degrees of freedom. By allowing for small currents (of heat or particles, for instance), the theory of linearly irreversible thermodynamics will be developed. A major insight will be the occurrence of cross-coupling effects, like the Peltier and Soret effect, obeying important symmetries (Onsager relations, Nobel Prize in Chemistry 1968). The occurrence of instabilities (I. Prigogine, Nobel Prize in Chemistry 1977) will also be discussed. We will then switch to the microscopic scale and motivate the famous Boltzmann equation, the foundation of transport theory. We will solve it by several approximation methods and use it to derive macroscopic balance equations, yielding a microscopic foundation of the processes described in the first part of the lecture. Finally, we make a close connection to equilibrium statistical physics, by discussing linear response theory and deriving the fluctuation-dissipation theorem. The main insight will be that the response of a system to a small perturbation, i.e. the outcome of a non-equilibrium situation, can be calculated within equilibrium theory. If time permits, at the end we will discuss few current research topics, like the use of Boltzmann-type equations in the modeling of 'active' systems (collective motion of animals, dynamics of cellular extracts) and the occurrence of nonequilibrium phase transitions in boundary-driven transport (asymmetric exclusion processes).

After a (condensed) review of the Standard Model of Particle Physics and of features of nature that we do not yet understand, I will present ways to extend the SM at high energies and (theoretical and experimental) guidance we have on our road to find out how nature could look like at shortest distances. Topics covered in the lecture include Electroweak Symmetry Breaking and its Dynamics, Models of a Composite Higgs, Supersymmetry, Extra Dimensions, and further approaches to understand the puzzling hierarchies we observe in nature. Moreover, I will discuss Effective Field Theory, Flavor Physics & Neutrino Masses, Dark Matter, Baryogenesis and other aspects of Cosmology, as well as the Strong CP Problem and Axions.

This interdisciplinary block seminar addresses students after the 4th semester from physics, biology, molecular biotechnology, molecular systems engineering and related fields. It is jointly organized by Friedrich Frischknecht (medicine, biology, parasitology), Christine Selhuber-Unkel (experimental biophysics) and Falko Ziebert and Ulrich Schwarz (theoretical biophysics). In our Vorbesprechung on Mon Oct 13 2025 at 4.15 pm, INF 267 (BioQuant), SR 44, we will fix the dates and distribute the subjects. The ability to move is one of the most fundamental features of biological cells and nearly as important as their ability to grow and divide. A notable exception from this observation is the case of plant cells. However, most other cell types, including bacteria, unicellular eukaryotes and animal cells, usually require some kind of motility in order to function properly. Understanding how cells move is not only interesting from an academic point of view, it is also a subject of large practical relevance, ranging from the design of artificial motility in materials science to medical applications like the control of malaria infection or cancer metastasis. In this seminar, we will introduce the fundamental biological and physical mechanisms underlying cell motility, and discuss state-of-the-art research in this interdisciplinary research field. The most important physical restrictions for cell motility are that (1) cells are small (typical size 10 micrometer) and (2) immersed in water, which on their small scale is extremely viscous (as quantified by the Reynolds number). One important aspect of the seminar will be to learn about the specific consequences of this situation. In the first half, we will discuss swimming microorganisms, like bacteria, algae, sperm or the parasite trypanosome, which typically move by rotating or beating a flagellum. In the second half, we will discuss cells which crawl or glide on surfaces, like human tissue cells, cancer cells, amoebae or malaria parasites. Every participant will receive a description of his/her subject and some relevant papers. While preparing your talk, you can meet with the organizers, who will answer questions and give feedback. The talks are then given typically in groups of two or three students, and in three or four blocks in January 2026. This will be counted as obligatory seminar for bachelor students (PSEM, 2+1 CPs) and a mark will be reported for your transcript. For physics master students, you can get 6 CPs for an obligatory master seminar (MVSem), but for this you also have to hand in a 15-20 pages written paper on your subject after the seminar is finished. Similar rules apply for students from other faculties. Active participation during discussions is expected.

Stochastic dynamics is the study of dynamical processes that occur on sufficiently large time scales such that the fast microscopic degrees of freedom can be effectively described by stochastic noise. The paradigmatic case is the movement of a Brownian particle (e.g. a plastic bead of micrometer dimensions) in a fluid (e.g. water). Then the particle trajectory performs a random walk effected by the random forces exerted by the molecules of the fluid ("Brownian dynamics"). The mathematical tool required to describe this situation is a stochastic differential equations, also known as the Langevin equation. Alternatively one can use the Fokker-Planck equation, which is a partial differential equation for the probability density p(x,t) of the particle to be at position x at time t. For stochastic processes with jumps, the appropriate equation is the master equation. Stochastic dynamics has many applications in physics, chemistry, biology and economics. In this course, we will provide an introduction into the fundamentals of this field, in particular to the three fundamental types of equations. We also will discuss how the classical theory can be extended to active systems, in particular the Active Brownian Particle (ABP) model for self-propelled objects, like e.g. bacteria. Applications will be chosen from the fields of (active) soft matter, biophysics, finance and machine learning. We will also discuss the path integral approach to stochastic processes as well as recent developments in non-equilibrium physics and stochastic thermodynamics. The course is designed for physics students in advanced bachelor and beginning master semesters, but students from other disciplines are also welcome. It will be given in English. A basic understanding of physics and differential equations is sufficient to attend. A background in statistical physics is helpful, but not required. The course takes place every Monday from 2.15 - 3.45 pm in lecture hall HS2 in INF 308 (Hörsaalgebäude). Every second week on Monday afternoons after the lecture the solutions to the exercises will be discussed in a tutorial. If you attend the course and solve more than 60 percent of the exercises, you earn 4 credit points. To get a grade, you have to pass an oral examination. A script is available from earlier versions of this course.

Continuum mechanics describes the movement of matter under force on a scale that is sufficiently large as to use continuous variables. Therefore continuum mechanics is an example of a classical field theory, like electrodynamics. Continuum mechanics is further subdivided into hydrodynamis (flow) and solid mechanics (deformation). Both fields are connected by the theory of viscoelasticity (flow of complex fluids, rheology). After a general introduction, we will focus on solid mechanics, but also cover some viscoelasticity. We also will discuss modern applications of continuum mechanics, in particular to the questions of how to deal with growth and active stresses in biological systems. Finally we will also cover numerical approaches to continuum mechanics, namely the finite element method (FEM) and its implementation in open source code like Fenics. Major subjects in this part will be 1. scalar elasticity 2. material laws and constitutive equations 3. viscoelasticity 4. Hookean solid, Newtonian fluid, Maxwell model, Kelvin-Voigt model 5. complex modulus 6. stress and strain tensors 7. Lagrangian versus Eulerian coordinates 8. geometrical and material non-linearities 9. linear elasticity theory 10. rods and plates 11. contact problems 12. non-linear elasticity theory, neo-Hookean solid 13. fracture and plasticity 14. thermoelasticity 15. active stresses 16. growth The course is designed for physics students in advanced bachelor and beginning master semesters, but students from other disciplines are also welcome. It will be given in English. A basic understanding of physics and differential equations is sufficient to attend. The course takes place every Wednesday from 11.15 - 13.00 at Philosophenweg 12. Every second week on Monday afternoons at 4 pm the solutions to the exercises will be discussed in a tutorial. If you attend the course and solve more than 60 percent of the exercises, you earn 4 credit points. To get a grade, you have to pass an oral examination.

https://hci.iwr.uni-heidelberg.de/content/optml-seminar-WiSe25 Attention! The webpage above is down (file server failure) and it may take a while to repair it. The most important information is provided therefore here: ## Topic: Bayesian Optimization Bayesian optimization is a well-established and powerful framework for tuning parameters and hyperparameters in settings where evaluating the objective function is expensive, time-consuming, or noisy. It is particularly valuable when the search space is continuous or high-dimensional, and gradient information is unavailable or unreliable. By modeling the objective function probabilistically—typically using Gaussian processes or other surrogate models—Bayesian optimization balances exploration (searching uncertain regions) and exploitation (refining promising areas), often achieving near-optimal results with far fewer evaluations than exhaustive search. Its applications span a broad spectrum: - Machine learning – hyperparameter tuning for models like neural networks, SVMs, and gradient boosting. - Engineering – optimizing design parameters in simulations or experiments. - Robotics – tuning control policies where real-world trials are costly. - Scientific computing – calibrating complex physical models. - Finance and operations research – optimizing trading strategies or decision processes. Numerous ready-to-use software packages, such as Spearmint, GPyOpt, scikit-optimize, and Ax, make these techniques widely accessible. The papers we discuss in the **Tutorials** provide a deep dive into the theoretical foundations, algorithmic variations, and practical considerations of Bayesian optimization, enabling you to apply it effectively to diverse real-world problems. ## Participation: Thursdays, 11:00-13:00 in Mathematikon B, R.B128 (3 OG) The first seminar takes place on Thu, Oct 16.

As most of the radiation we receive from galaxies is star light, we can use it to measure and study their properties. These lectures aim at showing how much we can learn about galaxy evolution from the study of stellar populations in galaxies (young to old stellar clusters, field stars, resolved and integrated stellar populations). We will review the methods commonly used in this respect, all resting on our understanding of stellar evolution, and discuss the results obtained when we apply them to observational data, such as multi-wavelength photometry and spectroscopy.

Stellar structure, evolution and explosions, including practical tutorials based on the MESA stellar evolution code. In the first half of the term, teaching will be via classical blackboard-style lectures that lay the foundation of stellar evolution. In contrast to classical lectures on stellar astrophysics, the second half is a practical course where students employ the stellar evolution code MESA to study the evolution and final fates of low-, intermediate- and high-mass stars. This allows us to follow the evolution of stars interactively, enabling us to investigate stellar structures in great detail. For the practical part, a laptop is required (all operating systems are supported). All course materials will be provided online.

In dieser Vorlesung für Neugierige, sprich: für Hörer*innen aller Fachbereiche, beschäftigen wir uns mit dem aktuellen Stand der Erforschung sowohl unseres Sonnensystems als auch seiner entfernten Verwandten: der Exoplaneten, die andere Sterne umkreisen als die Sonne. Wir schauen uns dazu nicht nur die Eigenschaften der bislang bekannten Planeten und Kleinkörper an, sondern beschäftigen uns auch mit Beobachtungsmethoden sowie mit der Frage, wie unser Sonnensystem und andere Sonnensysteme überhaupt entstanden sind.
