Non-Abelian (2,0)-Super-Yang-Mills Coupled to Nonlinear Sigma-Models
M. S. Goes-Negrao, J. A. Helayel-Neto, M. R. Negrao
Following a previous work on Abelian (2,0)-gauge theories, one reassesses here the task of coupling (2,0) relaxed Yang-Mills super-potentials to a (2,0)-nonlinear Sigma-model, by g…
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…
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…
