Axion-Photon Interaction from Nonminimal Dimension-5 Lorentz-Violating Operators
A. J. G. Carvalho, A. G. Dias, A. F. Ferrari +3
In this paper, we discuss various possible schemes for the perturbative generation of the axion-photon interaction term in different Lorentz-breaking extensions of QED, involving o…
model in aether-superspace
A. F. Ferrari, A. C. Lehum
In this paper we study the dynamical generation of mass in the Lorentz-violating model defined in two and three-dimensional aether-superspace. We show that even though…
Generation of Axion-Like Couplings via Quantum Corrections in a Lorentz Violating Background
L. H. C. Borges, A. G. Dias, A. F. Ferrari +2
Light pseudoscalars, or axion like particles (ALPs), are much studied due to their potential relevance to the fields of particle physics, astrophysics and cosmology. The most relev…
Lorentz violation in the linearized gravity
A. F. Ferrari, A. Yu. Petrov
We study some consequences of the introduction of a Lorentz-violating modification term in the linearized gravity, which leads to modified dispersion relations for gravitational wa…
Horava-Lifshitz modifications of the Casimir effect
A. F. Ferrari, H. O. Girotti, M. Gomes +2
We study the modifications induced by spacetime anisotropy on the Casimir effect in the case of two parallel plates. Nonperturbative and perturbative regimes are analyzed. In the f…
The 1/N Expansion in Noncommutative Quantum Mechanics
A. F. Ferrari, M. Gomes, C. A. Stechhahn
We study the 1/N expansion in noncommutative quantum mechanics for the anharmonic and Coulombian potentials. The expansion for the anharmonic oscillator presented good convergence…
