Vacuum-induced current density from a magnetic flux threading a cosmic dispiration in -dimensional spacetime
Herondy Mota
We investigate the vacuum-induced current density for a charged scalar field in a -dimensional cosmic dispiration spacetime threaded by a magnetic flux. This background comb…
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…
Vacuum Energy and Topological Mass in Interacting Elko and Scalar Field Theories
A. J. D. Farias Junior, A. Smirnov, Herondy F. Santana Mota +1
In this paper, we consider a four-dimensional system composed of a mass-dimension-one fermionic field, also known as Elko, interacting with a real scalar field. Our main objective…
Cylindrical boundary induced current in the cosmic string spacetime
E. R. Bezerra de Mello, H. F. Santana Mota, W. Oliveira dos Santos
In this paper we investigate the vacuum current associated with a charged bosonic field operator, induced by a cylindrical boundary in the idealized cosmic string spacetime. In thi…
Vacuum energy density from a self-interacting scalar field in a Lorentz-violating Horava-Lifshitz model
A. J. D. Farias Junior, E. R. Bezerra de Mello, Herondy Mota
In this paper we consider a massive self-interacting scalar quantum field in a Lorentz-violation scenario based on a Horava-Lifshitz model. Specifically, we investigate the vacuum…
