Induced current by a magnetic flux in dimensional conical spacetime in a Ho{Å}ava-Lifshitz Lorentz-violating scenario
E. R. Bezerra de Mello, H. F. Santana Mota
We investigate the vacuum expectation value of bosonic current induced by a magnetic flux in a dimensional conical spacetime in the presence of a circular boundary, in a Ho…
Thermal correction on the Casimir energy in a Horava-Lifshitz Lorentz-violating scenario
E. R. Bezerra de Mello, Herondy F. Mota
The Casimir effect is considered a great triumph of Quantum Field Theory. Originally the Casimir energy was investigated considering the vacuum fluctuation associated with electrom…
Probing Lorentz symmetry violation via the Casimir effect in rectangular cavities
M. B. Cruz, E. R. Bezerra de Mello, A. MartÃn-Ruiz
We investigate the Casimir effect as a probe of Lorentz symmetry violation for a real scalar field confined to a rectangular waveguide with Dirichlet boundary conditions. The field…
Current density induced by a cosmic string in de Sitter spacetime in the presence of two flat boundaries
W. Oliveira dos Santos, H. F. Santana Mota, E. R. Bezerra de Mello
In this paper, we investigate the vacuum bosonic current density induced by a carrying-magnetic-flux cosmic string in a -de Sitter spacetime considering the presence of two…
Vacuum energy density for interacting real and complex scalar fields in a Lorentz symmetry violation scenario
A. J. D. Farias Junior, A. Smirnov, Herondy F. Santana Mota +1
In this paper the vacuum energy density and generation of topological mass are investigated for a system of a real and complex scalar fields interacting with each other. In additio…
