Microstate continuum
Encyclopedia
A microstate continuum is the fluctuation spectrum of a thermodynamic system
in the classical limit of high temperatures. Classical here is to be understood in opposition to quantum statistical mechanics

Quantum statistical mechanics
Quantum statistical mechanics is the study of statistical ensembles of quantum mechanical systems. A statistical ensemble is described by a density operator S, which is a non-negative, self-adjoint, trace-class operator of trace 1 on the Hilbert space H describing the quantum system. This can be...
