Hidden gauge structure and derivation of microcanonical ensemble theory of bosons from quantum principles
arXiv:cond-mat/0205666 · doi:10.1103/PhysRevE.67.036119
Abstract
Microcanonical ensemble theory of bosons is derived from quantum mechanics by making use of a hidden gauge structure. The relative phase interaction associated with this gauge structure, described by the Pegg-Barnett formalism, is shown to lead to perfect decoherence in the thermodynamics limit and the principle of equal a priori probability, simultaneously.
