Last update: T_UTF (25.04.2003)

Strongly interacting particles, lattice models, electron-electron and electron-phonon interaction. Self-consistent approximations for strongly correlated electrons: functional integral and saddle-point method, static approximation, the mean-field method and the limit of large dimensions. Quantum dynamical phenomena: Kondo effect and the formation of local magnetic moments, theory of magnetism in transition metals. Microscopic theory of superconductivity. Exactly solvable models - Bethe ansatz for correlated electrons. The course follows TMF031.

Zkouška je ústní. Každý student dostane tři otázky, z nichž jedna je početního charakteru, aby student prokázal zvládnutí použitý naučeného formalismu. Požadavky ke zkoušce se kryjí se sylabem a dostupným skriptem s omezením na skutečně probranou látku v kursu. K získání zkoušky je třeba zvládnout početní otázku a alespoň jednu metodickou otázku.
