Spin-1/2 particles in Phase space: Casimir effect and Stefan-Boltzmann law at finite temperature
R. G. G. Amorim, S. C. Ulhoa, J. S da Cruz Filho +2
The Dirac field, spin 1/2 particles, is investigated in phase space. The Dirac propagator is defined. The Thermo Field Dynamics (TFD) formalism is used to introduce finite temperat…

On Scalar Electromagnetism in Phase Space
R. G. G. Amorim, J. S da Cruz Filho, A. F. Santos +1
In this paper the interaction of a scalar field and the electromagnetic field in phase space is analyzed. The scattering process is calculated up to first order in the Planck const…

Stefan-Boltzmann law and Casimir effect for the scalar field in phase space at finite temperature
R. G. G. Amorim, J. S da Cruz Filho, A. F. Santos +1
In this paper we use the scalar field constructed in phase space to analyze the analogous Stefan-Boltzman law and Casimir effect both of them at finite temperature. The temperature…
