Some dynamical properties of a classical dissipative bouncing ball model with two nonlinearities
(2013-04-15)
Some dynamical properties for a bouncing ball model are studied. We show that when dissipation is introduced the structure of the phase space is changed and attractors appear. Increasing the amount of dissipation, the edges ...
Saddle points and rare collisions under scaling approach in a Fermi accelerator with two nonlinear terms
(2013-04-01)
Rare collisions of a classical particle bouncing between two walls are studied. The dynamics is described by a two-dimensional, nonlinear and area-preserving mapping in the variables velocity and time at the instant that ...
The Thermal Statistics of Quasi-Probabilities' Analogs in Phase Space
(Hindawi Publishing Corporation, 2015-09)
We focus attention upon the thermal statistics of the classical analogs of quasi-probabilities (QP) in phase space for the important case of quadratic Hamiltonians. We consider the three more important OPs: Wigner's, P -, ...
Dinâmica de sistemas bipartites de spins no espaço de fase quântico discreto
(Universidade Estadual Paulista (Unesp), 2010-02-22)
Quando temos sistemas quânticos sem análogo clássico a descrição de Weyl- Wigner, para o espaço de fase quântico, não pode ser utilizada, pois a mesma não representa graus de liberdade associados a grandezas discretas. Um ...

Verlinde’s emergent gravity in an n -dimensional, non-additive Tsallis’ scenario
(Elsevier Science, 2018-09)
This paper brings together four distinct but very important physical notions: Entropic force, Entropy-along-a-curve, Tsallis? q-statistics, and Emergent gravitation. We investigate the non additive, classical (Tsallis?) ...
