Coupling Nonlinear Sigma-Models to Relaxed Yang- Mills Supermultiplets in (2,0)-Superspace

M. S. Goes-Negrao, J. A. Helayel-Neto, and 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 superpotentials to a (2,0)- nonlinear -model, by gau…

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…

(2,0)-Super-Yang-Mills Coupled to Non-Linear Sigma-Model

M. S. Goes-Negrao, M. R. Negrao, A. B. Penna-Firme

Considering a class of (2,0)-super-Yang-Mills multiplets that accommodate a pair of independent gauge potentials in connection with a single symmetry group, we present here their c…

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…
