Mathematical Methods of Condensed Matter Physics

Course Type: 
PhD Course
Academic Year: 
October - April
60 h
  • The course will discuss rigorous results in quantum mechanics and in statistical mechanics, relevant for condensed matter physics. Topics to be covered include:


  1. Elements of spectral theory, with applications to lattice Schroedinger operators.
  2. Effect of disorder on quantum dynamics. The Anderson model, and its phase diagram.
  3. Relation between spectra and dynamics: the RAGE theorem.
  4. Anderson localization through path expansions.
  5. Quantum transport, heuristic linear response theory. Making it rigorous: the adiabatic theorem.
  6. Quantum Hall effect. Bulk-edge correspondence.
  7. Time-reversal invariant systems. Example: Kane-Mele model. Z2 classification and bulk-edge duality.
  8. Interacting lattice models. Grand canonical formulation, Fock space, perturbation theory.
  9. Cluster expansion, convergence of fermionic perturbation theory, analyticity of the Gibbs state.
  10. Approach to criticality: the rigorous renormalization group. Applications: interacting graphene, nonintegrable perturbations of the 2d Ising model. Construction of a nontrivial RG fixed point: lattice models with long range hoppings.
  11. Universality of transport in quantum Hall systems and semimetals.
