Generalized Neumann boundary condition for the scalar field
J. C. Fernandes, J. P. Ferreira, F. E. Barone +3
In this paper, we explore the Klein-Gordon field theory in dimensions in the presence of a -dimensional hyperplanar -like potential that couples quadratically to…
Magnetoelectric boundary simulated by a Chern-Simons-like model
H. L. Oliveira, L. H. C. Borges, F. E. Barone +1
In this work we study some physical phenomena that emerge in the vicinity of a magnetoelectric boundary. For simplicity, we restrict to the case of a planar boundary described by a…
New point-like sources and a conducting surface in Maxwell-Chern-Simons electrodynamics
L. H. C. Borges, F. E. Barone, C. C. H. Ribeiro +3
We investigate some aspects of the Maxwell-Chern-Simons electrodynamics focusing on physical effects produced by the presence of stationary sources and a perfectly conducting plate…
Higher order derivative operators as quantum corrections
L. H. C. Borges, F. A. Barone, C. A. M. de Melo +1
In this paper we propose a non-minimal, and ghost free, coupling between the gauge field and the fermionic one from which we obtain, perturbatively, terms with higher order derivat…
Effects of the fermionic vacuum polarization in QED
M. F. X. P. Medeiros, F. E. Barone, F. A. Barone
Some effects of vacuum polarization in QED due to the presence of field sources are investigated. We focus on effects with no counter-part in Maxwell electrodynamics. The the Uehli…
Field theoretic description of electromagnetic boundaries: The Casimir effect between dissimilar mirrors from external potentials
F. E. Barone, F. A. Barone
In a previous work we formulated a model of semitransparent dielectric surfaces, coupled to the electromagnetic field by means of an effective potential. Here we consider a setup w…
Field theoretic description of partially reflective surfaces
F. E. Barone, F. A. Barone
The issue of electric charges in interaction with partially reflective surfaces is addressed by means of field theoretic methods. It is proposed an enlarged Maxwell lagrangian, des…
Interactions between delta-like sources and potentials
G. T. Camilo, F. E. Barone, F. A. Barone
The modified scalar boson propagator due to the presence of a hyperplane semi-transparent mirror is computed. From this, the classical interaction between static charges and the mi…
Consequences of vacuum polarization on electromagnetic waves in a Lorentz-symmetry breaking scenario
B. Agostini, F. A. Barone, F. E. Barone +2
The propagation of electromagnetic waves in a Lorentz-symmetry violating scenario where there is a region of polarized vacuum is studied. It turns out that the photon field acquire…
Charged branes interactions via Kalb-Ramond field
F. A. Barone, F. E. Barone, J. A. Helayel-Neto
Because of its versatility, the 2-form field has been employed to describe a multitude of scenarios that range from high energy to condensed matter physics. Pushing forward in this…
