The quantum canonical ensemble in phase space

Introduction to special issue: Chaos Indicators, Phase Space and Chemical Reaction Dynamics

“…The work [12] develops phase space analysis techniques combined with semiclassical approximations to obtain results concerning the variation of the equilibrium Gibbs ensemble as the temperature ranges from the deep quantum regime to the classical. In particular, it analyses the Gibbs state using its Wigner function, where the Gibbs state is viewed as a density matrix.…”
