Contribution

It introduces the use of hyperensembles as a tool for analyzing equilibrium systems, expanding their applicability beyond non-equilibrium contexts.

Findings

Hyperensembles can effectively describe equilibrium systems.

Application examples include ideal gas and Ising models.

Hyperensembles provide new insights into statistical physics models.

Abstract

The hyperensembles, introduced by Crooks in a context of non-equilibrium statistical physics, are considered here as a tool for systems in equilibrium. Simple examples like the ideal gas, the mean-field model, and the Ising interaction on small square lattices, are worked out to illustrate the concepts.
