Quantum forces in cavities
E. Cavalcanti, A. P. C. Malbouisson
We present an alternative route to investigate quantum forces in a cavity, for both a free scalar field and a free fermionic field. Considering a generalized Matsubara procedure, w…
Casimir effect via a generalized Matsubara formalism
Andreson L. C. Rego, C. A. Linhares, A. P. C. Malbouisson
We investigate the Casimir effect in the context of a nontrivial topology by means of a generalized Matsubara formalism. This is performed in the context of a scalar field in E…
Finite-size effects on the phase transition in a four- and six-fermion interaction model
L. M. Abreu, F. C. Khanna, A. P. C. Malbouisson +2
We consider four- and six-fermion interacting models at finite temperature and density. We construct the corresponding free energies and investigate the appearance of first- and se…
Realization of the Noncommutative Seiberg-Witten Gauge Theory by Fields in Phase Space
R. G. G. Amorim, F. C. Khanna, A. P. C. Malbouisson +2
Representations of the Poincaré symmetry are studied by using a Hilbert space with a phase space content. The states are described by wave functions ( quasi amplitudes of probabili…
Magnetic effects on spontaneous symmetry breaking/restoration in a toroidal topology
L. M. Abreu, C. A. Linhares, A. P. C. Malbouisson +1
We study temperature and finite-size effects on the spontaneous symmetry breaking/restoration for a scalar field model under the influence of an external magnetic field, at finite…
Uncertainty principle in a cavity at finite temperature
A. P. C. Malbouisson
We employ a dressed state approach to perform a study on the behavior of the uncertainty principle for a system in a heated cavity. We find, in a small cavity for a given temperatu…
