Abstract

 

Macroscopic phase coherence is one of the most remarkable manifestations of quantum mechanics,

yet it seems to be the inevitable ground state of interacting many-body systems.

In the last two decades, the familiar examples of superfluid He and conventional superconductors have been joined

by exotic and high temperature superconductors, ultra-cold atomic gases, both bosonic and fermionic, and recently

systems of excitons, magnons, and exciton-photon superpositions called polaritons, the subject of this talk.
