Horava-Lifshitz four-fermion model revisited and dynamical symmetry breaking
T. Mariz, J. R. Nascimento, A. Yu. Petrov
In this paper, we develop studies of the dynamical symmetry breaking in the Horava-Lifshitz four-fermion model for the specific case and explicitly demonstrate that for vario…
Podolsky electrodynamics from a condensation of topological defects
D. R. Granado, A. J. G. Carvalho, A. Yu. Petrov +1
In this paper we demonstrate the arising of higher-derivative contributions to the effective action of electrodynamics on the base of generalized Julia-Toulouse mechanism and expli…
Causality, unitarity, and indefinite metric in Maxwell-Chern-Simons extensions
Ricardo Avila, Jose R. Nascimento, Albert Yu. Petrov +2
We canonically quantize -dimensional electrodynamics including a higher-derivative Chern-Simons term. The effective theory describes a standard photon and an additional degr…
Metric-affine bumblebee gravity: classical aspects
Adria Delhom, J. R. Nascimento, Gonzalo J. Olmo +2
We consider the metric-affine formulation of bumblebee gravity, derive the field equations, and show that the connection can be written as Levi-Civita of a disformally related metr…
Renormalization Group Improvement of the Superpotential for the N=2 Chern-Simons-matter model
A. C. Lehum, J. R. Nascimento, A. Yu. Petrov +1
Within the superfield formalism, we study the renormalization group improvement of the effective superpotential for the Chern-Simons-matter theory, explicitly obtain t…
Perturbative aspects of mass-deformed N=3 Chern-Simons-matter theory
A. C. Lehum, J. R. Nascimento, A. Yu. Petrov
Within the superfield formalism, we calculate the two-point functions and the effective potential for the mass-deformed Chern-Simons-matter theory and discuss the rela…
