Lecture contents

Introduction to solid state physics. The complexity of 1023 particles interacting with each other in a solid gives 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 theores work our way into the contemporary theory of many particle physics. 

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
  • Relativistic corrections - spin-orbit coupling
  • Phase transitions and topology

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

  • Hartree-Fock
  • Density functional theory

Exercise sheets

Practice groups

  • Group 01 (Nicolo Defenu)
