V magistrski nalogi preučujem sklopljen elektronsko-fononski sistem, Holsteinov model za polaron, kot izoliran večdelčni kvantni sistem daleč od ravnovesja. Prvo vprašanje neravnovesne dinamike je problem ekvilibracije in termalizacije. Torej: zakaj in do katere mere lahko po dovolj dolgem času zapr ...

This thesis addresses transport questions in strongly correlated electronic systems in two dimensions. The primary tool for the analysis is the exact numerical treatment of the problem on small clusters, which allows for a description of transport at high temperatures, combined with dynamical mean-f ...

Stimulated by recent experiments on materials representing the realization of the anisotropic Heisenberg spin- 1/2 model on a triangular lattice (TL), we explore further properties of such a model in the easy-axis regime α = J⊥/Jz < 1 and the plausibility of finding effective models that capture sim ...
