Point-Like Charges and Dirichlet Boundary Conditions in a Nonlocal Scalar Field Theory
L. H. C. Borges, C. Filgueiras, F. A. Barone +1
In this paper, we investigate novel classical non-local effects in scalar field theory arising from the presence of external sources and a material boundary. Specifically, we consi…

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…

The role of scalar current coupling along surfaces
F. A. Barone, L. H. C. Borges, G. Flores-Hidalgo +2
In this paper we propose a coupling between the complex scalar field and an external Dirac delta-like planar potential. The coupling is achieved through the Klein-Gordon current no…
