Ph. D. thesis Quantum Phase Transitions in Correlated Systems
... In this thesis we shall investigate the properties of systems with strong correlations. Correlations are present even in ideal gases: at low temperatures, quantum statistics manifest in entirely different behavior of bosons and fermions. The situation gets more interesting and also more involved whe ...
