Finite quantum many fermion systems are essential for our current understanding of Nature.
They are at the core of molecular, atomic, and nuclear physics. In recent years, the …

We deal here with an exactly solvable N-nucleon system that has been used to mimic typical
features of quantum many-body systems. There is in the literature some controversy …

This work scrutinizes, using statistical mechanics indicators, important traits displayed by
quantum many-body systems. Our statistical mechanics quantifiers are employed, in the …

We provide a generalization of the approach to geometric probability advanced by the great
mathematician Gian Carlo Rota, in order to apply it to generalized probabilistic physical …

Statistical Mechanics (SM) has been quite successful in providing one with exact, or at least
approximate, descriptions of the time-dependent solutions of the Liouville (or of the von …

In this paper, we deal with the situation in which the unknown state of a quantum system has
to be estimated under the assumption that it is prepared obeying a known set of symmetries …

Arguments of the Jaynes maximum entropy sort have proved to be surprisingly successful in
providing one with approximate descriptions of pure states in a variety of scenarios, entirely …

We analyze the smoothness of the ground state energy of a one-parameter Hamiltonian by
studying the differential geometry of the numerical range and continuity of the maximum …

The objective of this work is to show that simple modifications in the form of the fermion–
fermion interacting potential generate widely different thermodynamic behaviors, with …
