Statistical complexity in an SU(2) × SU(2) many-fermion environment
(Elsevier Science, 2019-03)
We consider a typical many body problem. In particular, we study an exactly solvable fermion system. We apply to it recently developed statistical quantifiers like the statistical complexity C and the disequilibrium D. The ...
Spectral explanation for statistical odd-even staggering in few fermions systems
(MDPI AG, 2021-03)
Odd-even statistical staggering in a Lipkin-like few fermions model has been recently encountered. Of course, staggering in nuclear binding energies is a well established fact. Similar effects are detected in other finite ...
Statistical complexity of the coriolis antipairing effect
(Molecular Diversity Preservation International, 2019-06)
Using the entropic quantifier called statistical complexity, we investigate the interplay between (1) pairing interactions between fermions, can be viewed as analogous with superconductivity based on Cooper pairs; (2) ...
Exact and quasiexact solvability of second order superintegrable quantum systems. II. Relation to separation of variables
(2007)
We make explicit the intimate relationship between quasiexact solvability, as expounded, for example, by Ushveridze [Quasi-exactly Solvable Models in Quantum Mechanics (IOP, Bristol, 1993)], and the technique of separation ...
Body motion in a resistive medium: an exactly solvable model
(Sociedad Mexicana de Fisica, 2001)
We introduce and solve in closed form, using momentum and kinetic energy balance, a simplified microscopic model of a body propagating in a one dimensional resistive medium. For a whole family of collisions with varying ...
Unbiased diffusion of Brownian particles on disordered correlated potentials
(IOP Publishing, 2015)
In this work we study the diffusion of non-interacting overdamped particles, moving on unbiased disordered correlated potentials, subjected to Gaussian white noise. We obtain an exact expression for the diffusion coefficient ...
Entanglement and the Born-Oppenheimer approximation in an exactly solvable quantum many-body system
(Springer, 2014-11)
We investigate the correlations between different bipartitions of an exactly solvable one-dimensional many-body Moshinsky model consisting of Nn nuclei and Ne electrons. We study the dependence of entanglement on the ...
