Resumen:
We focus attention upon the thermal statistics of the classical analogs of quasi-probabilities (QP) in phase space for the importantcase of quadratic Hamiltonians. We consider the three more important OPs: Wigner?s, 𝑃-, and Husimi?s. We show that, for allof them, the ensuing semiclassical entropy is a function only of the fluctuation product Δ𝑥Δ𝑝.We ascertain that the semiclassicalanalog of 𝑃-distribution seems to becomeunphysical at very lowtemperatures.Thebehavior of several other information quantifiersreconfirms such an assertion inmanifold ways.We also examine the behavior of the statistical complexity and of thermal quantitieslike the specific heat.
