Magnetic properties of confined bosonic vacuum at finite temperature
M. V. Cougo-Pinto, C. Farina, M. R. Negrao
We compute the combined effect of confinement, an external magnetic field and temperature on the vacuum of the charged scalar field using Schwinger's formula for the effective acti…
Casimir effect at finite temperature of charged scalar field
M. V. Cougo-Pinto, C. Farina, M. R. Negrao +1
The Casimir effect for Dirac as well as for scalar charged particles is influenced by external magnetic fields. It is also influenced by finite temperature. Here we consider the Ca…
Fermionic Casimir effect in an external magnetic field
M. V. Cougo-Pinto, C. Farina, A. C. Tort
The influence of an external constant uniform magnetic field on the Casimir energy density of a Dirac field under antiperiodic (and periodic) boundary condition is computed by appl…
Magnetic permeability of constrained scalar QED vacuum
M. V. Cougo-Pinto, C. Farina, M. R. Negrao +1
We compute the influence of boundary conditions on the Euler-Heisenberg effective Lagrangian scalar QED scalar for the case of a pure magnetic field. The boundary conditions constr…
