On the aether-like Lorentz-breaking actions
M. Gomes, J. R. Nascimento, A. Yu. Petrov +1
We demonstrate the generation of the CPT-even, aether-like Lorentz-breaking actions for the scalar and electromagnetic fields via their appropriate Lorentz-breaking coupling to spi…
Free energy of Lorentz-violating QED at high temperature
M. Gomes, T. Mariz, J. R. Nascimento +3
In this paper we study the one- and two-loop contribution to the free energy in QED with the Lorentz symmetry breaking introduced via constant CPT-even Lorentz-breaking parameters…
On the effective potential in higher-derivative superfield theories
M. Gomes, J. R. Nascimento, A. Yu. Petrov +1
We study the one-loop quantum corrections for higher-derivative superfield theories, generalizing the approach for calculating the superfield effective potential. In particular, we…
Dynamical noncommutativity
M. Gomes, V. G. Kupriyanov, A. J. da Silva
The model of dynamical noncommutativity is proposed. The system consists of two interrelated parts. The first of them describes the physical degrees of freedom with coordinates q^1…
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…
