Probing Lorentz symmetry violation via the Casimir effect in rectangular cavities
M. B. Cruz, E. R. Bezerra de Mello, A. Martín-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…
Induced Fermionic vacuum polarization in dS spacetime with a compactified cosmic string
E. A. F. Bragança, E. R. Bezerra de Mello, A. Mohammadi
We study the fermionic condensate (FC) and the vacuum expectation value (VEV) of the energy-momentum tensor for a massive spinor field in the de Sitter (dS) spacetime including an…
Vacuum polarization in high-dimensional AdS spacetime in the presence of a cosmic string and compactified extra dimension
W. Oliveira dos Santos, E. R. Bezerra de Mello, H. F. Mota
In this paper, we analyze the vacuum expectation values (VEVs) of the field squared and the energy-momentum tensor associated with a charged and massive scalar quantum field in a g…
Induced current in high-dimensional AdS spacetime in the presence of a cosmic string and a compactified extra dimension
W. Oliveira dos Santos, H. F. Mota, E. R. Bezerra de Mello
In this paper, we analyse the bosonic current densities induced by a magnetic flux running along the core of an idealized cosmic string in a high-dimensional AdS spacetime, admitti…
Thermal corrections to the Casimir energy in a Lorentz-breaking scalar field theory
M. B. Cruz, E. R. Bezerra de Mello, A. Yu. Petrov
In this paper, we investigate the thermal effect on the Casimir energy associated with a massive scalar quantum field confined between two large parallel plates in a CPT-even, aeth…
