Lee-Yang theory of the superradiant phase transition in the open Dicke model
The Dicke model describes an ensemble of two-level atoms that are coupled to a confined
light mode of an optical cavity. Above a critical coupling, the cavity becomes macroscopically …

Lee-Yang theory of Bose-Einstein condensation
Bose-Einstein condensation happens as a gas of bosons is cooled below its transition
temperature, and the ground state becomes macroscopically occupied. The phase transition …
