Density Matrix of a Bose--Einstein Condensate: Steady--State versus Mean--Field Approach
S. J. Wang, M. C. Nemes, A. N. Salgueiro +1
We compare the equilibrium solution for the condensate obtained in the mean--field approximation to the master equation for sympathetic cooling with the one obtained by Scully for…
Mean-Field Approximation to the Master Equation for Sympathetic Cooling of Trapped Bosons
S. J. Wang, M. C. Nemes, A. N. Salgueiro +1
We use the mean-field approximation to simplify the master equation for sympathetic cooling of Bosons. For the mean single-particle occupation numbers, this approach yields the sam…
On the Renormalization of a Bosonized Version of the Chiral Fermion-Meson Model at Finite Temperature
H. C. de Godoy Caldas, M. C. Nemes
Feynman's functional formulation of statistical mechanics is used to study the renormalizability of the well known Linear Chiral Sigma Model in the presence of fermionic fields at…
Recoherence in the entanglement dynamics and classical orbits in the N-atom Jaynes-Cummings model
Renato M. Angelo, Kyoko Furuya, M. Carolina Nemes +1
The rise in linear entropy of a subsystem in the N-atom Jaynes-Cummings model is shown to be strongly influenced by the shape of the classical orbits of the underlying classical ph…
Modelling the Recoherence of Mesoscopic Superpositions in Dissipative Environments
S. G. Mokarzel, A. N. Salgueiro, M. C. Nemes
A model is presented to describe the recently proposed experiment (J. Raimond, M. Brune and S. Haroche Phys. Rev. Lett {\bf 79}, 1964 (1997)) where a mesoscopic superposition of ra…
Chiral Anomaly and CPT invariance in an implicit momentum space regularization framework
A. P. Baeta Scarpelli, M. Sampaio, M. C. Nemes +1
This is the second in a series of two contributions in which we set out to establish a novel momentum space framework to treat field theoretical infinities in perturbative calculat…
N-loop Treatment of Overlapping Diagrams by the Implicit Regularization Technique
S. R. Gobira, M. C. Nemes
We show how the Implicit Regularization Technique (IRT) can be used for the perturbative renormalization of a simple field theoretical model, generally used as a test theory for ne…
