Theoretical Condensed Matter Physics

Lecture (physics617)


Time:   Wed 14-15, Fri 10-12

Place:  HS, IAP



  • Periodic lattice structures:
    Discrete symmetry groups, Bravais lattice, lattice with basis, lattice types.
    Reciprocal lattice, Brillouin zone, Bloch theorem, band structure.
  • Fermi liquid theory:
    Concept of continuity
    Fermionic quasiparticles, collective modes of the Fermi liquid,
    particle-hole excitations and excitons
  • Collective excitations of the Lattice: phonons
    Einstein model, Debye model
  • Phase transitions (general):  Mean-field theory  
  • Magnetism and collectice magnetic excitations: spin waves, magnons
  • Mixed electronic and photonic excitations in solids: polaritons
  • Superconductivity: BCS theory



The exercise sheets will be handed out every week on Friday and are due for the next week, Friday in class or room PI 1.055. The exercises can be done in groups of maximum 3 persons.
