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…
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…
Coleman-Weinberg mechanism in a three-dimensional supersymmetric Chern-Simons-matter model
A. F. Ferrari, E. A. Gallegos, M. Gomes +4
Using the superfield formalism, we study the dynamical breaking of gauge symmetry in the N=1 three-dimensional supersymmetric Chern-Simons model, coupled to a complex scalar superf…
On the superfield effective potential in three dimensions
A. F. Ferrari, M. Gomes, A. C. Lehum +4
We develop the superfield approach to the effective potential in three dimensions and calculate the one-loop and two-loop kählerian effective potential in commutative and noncommut…
