The Role of Mass and External Field on the Fermionic Casimir Effect
J. L. Tomazelli, L. C. Costa
The aim of this work is to investigate the role played by the fermion mass and that of an external field on the fermionic Casimir energy density under S^1 X R^3 topology. Both twis…

The Euler-Kockel-Heisenberg Lagrangian at Finite Temperature
J. L. Tomazelli, L. C. Costa
In the present work we investigate temperature effects on the spinor and scalar effetive QED in the context of Thermo Field Dynamics. Following Weisskopf's zero-point energy method…

Vacuum Polarization Effects from Fermion Zero-Point Energy
J. L. Tomazelli
The influence of an external electromagnetic field on the vacuum structure of a quantized Dirac field is investigated by considering the quantum corrections to classical Maxwell's…
