Thermodynamic Framework for Compact q-Gaussian Distributions
Andre M. C. Souza, Roberto F. S. Andrade, Fernando D. Nobre +1
Recent works have associated systems of particles, characterized by short-range repulsive interactions and evolving under overdamped motion, to a nonlinear Fokker-Planck equation w…
Entanglement can preserve the compact nature of the phase-space occupancy
Andre M. C. Souza, Peter Rapčan, Constantino Tsallis
We study the one-dimensional transverse-field spin-1/2 Ising ferromagnet at its critical point. We consider an -sized subsystem of a -sized ring, and trace over the states of…
Generalizing Planck's distribution by using the Carati-Galgani model of molecular collisions
R. D. B. Carvalho, A. M. C. Souza
Classical systems of coupled harmonic oscillators are studied using the Carati-Galgani model. We investigate the consequences for Einstein's conjecture by considering that the exch…
Describing the ground state of quantum systems through statistical mechanics
Andre M. C. Souza
We present a statistical mechanics description to study the ground state of quantum systems. In this approach, averages for the complete system are calculated over the non-interact…
A simple model for magnetism in itinerant electron systems
Andre M. C. Souza
A new lattice model of interacting electrons is presented. It can be viewed as a classical Hubbard model in which the energy associated to electron itinerance is proportional to th…
Generalizing the Planck distribution
Andre M. C. Souza, Constantino Tsallis
Along the lines of nonextensive statistical mechanics, based on the entropy , and Beck-Cohen superstatistics, we heurist…
