چکیده

Abstract In these lectures, starting with a review of secondand coherent-state path-integral quantization, we will formulate a quantum field theory of bosonic matter and will study its thermodynamics and correlation functions. We will explore the transition to Bose-Einstein condensation (BEC) of noninteracting bosons. Including interactions, we will study the properties of a superfluid and a phase transition into it within a mean-field theory, quantum “hydrodynamics”, Bogoluibov theory and Lee-Huang-Yang expansion of a weakly interacting Bose gas.

2 1 N ov 2 00 5 Exotic quantum phases and phase transitions in correlated matter ⋆

We present a pedagogical overview of recent theoretical work on unconventional quantum phases and quantum phase transitions in condensed matter systems. Strong correlations between electrons can lead to a breakdown of two traditional paradigms of solid state physics: Landau’s theories of Fermi liquids and phase transitions. We discuss two resulting “exotic” states of matter: topological and cri...
