Fermionic Casimir effect in an axial Lorentz-violating background
A. Martín-Ruiz, M. B. Cruz, E. R. Bezerra de Mello
We investigate the fermionic Casimir effect for a Dirac field confined between two parallel plates with MIT bag boundary conditions in the presence of CPT-odd Lorentz-symmetry viol…

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…

Induced current in high-dimensional AdS bulk in the presence of a cosmic string and brane
W. Oliveira dos Santos, E. R. Bezerra de Mello
In this paper we analyze the vacuum bosonic current associated with a massive charged scalar field propagating in a -dimensional anti-de Sitter (AdS) bulk in the presence of…
