Stabilita Fermiho kapaliny vůči dynamickým fluktuacím v silně korelovaných elektronových systémech
In this thesis, we study quantum impurity models by means of the diagrammatic perturbation theory. First, parquet equations are simplified in the strong coupling regime and low temperatures and an analytically controllable approximation results. We apply it to both the single impurity Anderson model...
