Dual equivalence between the Maxwell-Chern-Simons theory and two self-dual massive models interacting with matter in , superspace
F. S. Gama, J. R. Nascimento, A. Yu. Petrov +1
We investigate the supersymmetric generalization of the dual equivalence between the Maxwell-Chern-Simons model and two massive self-dual models. One of the self-…
Generalized Chern-Pontryagin models
J. R. Nascimento, A. Yu. Petrov, P. J. Porfírio +1
We formulate a new class of modified gravity models, that is, generalized four-dimensional Chern-Pontryagin models, whose action is characterized by an arbitrary function of the Ri…
Derivative four-fermion model, effective action and bumblebee generation
R. Araujo, T. Mariz, J. R. Nascimento +1
In this paper, we study the one-loop effective potential of a derivative four-fermion model. As a result, an exact bumblebee-like potential is radiatively generated. Afterwards, we…
Modified Euler-Heisenberg effective action and Proper-Time Method in Lorentz-Violating Scalar QED
L. C. T. Brito, J. C. C. Felipe, A. C. Lehum +2
Quantum photon effects in vacuum provide an interesting setting to test quantum electrodynamics, serving as a source for predictions about physics beyond the Standard Model. In thi…
One-loop corrections in Maxwell-metric-affine bumblebee gravity
A. C. Lehum, J. R. Nascimento, A. Yu. Petrov +1
In this paper, we consider the coupling of the metric-affine bumblebee gravity to the Abelian gauge field and obtain the effective model corresponding to the weak gravity limit of…
An exact stationary axisymmetric vacuum solution within a metric--affine bumblebee gravity
A. A. Araújo Filho, J. R. Nascimento, A. Yu. Petrov +1
Within the framework of the spontaneous Lorentz symmetry breaking, we consider a metric--affine generalization of the gravitational sector of the Standard--Model Extension (SME), i…
