Effective Lagrangian of a fermion field in a nontrivial topology under magnetic effects
Emerson B. S. Corrêa, Michelli S. R. Sarges, Airton H. G. Rodrigues +1
We have investigated a fermionic system from the perspective of an effective quantum field theory defined on a nontrivial topology in the presence of an external magnetic field. Us…

Green's functions under magnetic effects in a nontrivial topology
Emerson B. S Corrêa, Michelli S. R. Sarges, José A. Helayël-Neto
We calculate the Bose and Dirac field propagators in a four-dimensional Euclidean space under a magnetic external field by using a hybrid version of the Ritus and Schwinger methods…

Boundary conditions and electromagnetic effects on the phase transition of a zero spin bosonic system
Emerson B. S. Corrêa, Michelli S. R. Sarges
In the following paper, we will study a charged scalar field under an electromagnetic external field taking into account the spatial confining of the system. We shall use the Colem…
