Magnetic corrections to the fermionic Casimir effect with Lorentz symmetry violation and a compactified extra dimension

Andrea Erdas

The paper computes how a constant magnetic field alters the Casimir energy and pressure for a massive charged fermion with a‑ether‑type Lorentz‑violating term in a space that inclu…

Vacuum Energy and Topological Mass from a Constant Magnetic Field and Boundary Conditions in Coupled Scalar Field Theories

A. J. D. Farias Junior, Andrea Erdas, Herondy F. Santana Mota

We investigate the combined effects of a uniform magnetic field and boundary conditions on vacuum energy and topological mass generation in a coupled scalar field theory. The syste…

Finite temperature Casimir effect of a Lorentz-violating scalar with higher order derivatives

Andrea Erdas

In this work I study the finite temperature Casimir effect caused by a complex and massive scalar field that breaks Lorentz invariance in a CPT-even, aether-like manner. The Lorent…

Magnetic Casimir effect of a Lorentz-violating scalar with higher order derivatives

Andrea Erdas

In this paper I study the Casimir effect caused by a charged and massive scalar field that breaks Lorentz invariance in a CPT-even, aether-like manner. The breaking of Lorentz inva…

Fermionic Casimir effect at finite temperature in Horava-Lifshitz theories

Andrea Erdas

In this work, I study the finite temperature Casimir effect due to a massless fermion field that violates Lorentz invariance according to the Horava-Lifshitz theory. I investigate…

Casimir effect of a doubly Lorentz-violating scalar in magnetic field

Andrea Erdas

In this work I study the Casimir effect caused by a charged and massive scalar field that violates Lorentz symmetry in an aether-like and CPT even manner, by direct coupling betwee…
