Nonrelativistic effective potential of the bumblebee model

C. Furtado, J. R. Nascimento, A. Yu. Petrov +1

In this paper, we explicitly obtain the nonrelativistic Breit potential in the bumblebee model arising in the weak gravity limit of the metric-affine bumblebee gravity, coupled to…

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…

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-…

Global monopole in a Ricci-coupled Kalb-Ramond bumblebee gravity

F. M. Belchior, R. V. Maluf, A. Yu. Petrov +1

In this paper, we investigate black hole solutions in Einstein-Kalb-Ramond (EKR) bumblebee gravity sourced by a global monopole characterized by the charge . This modified theo…

Kink solutions in nonlocal scalar field theory models

I. Andrade, R. Menezes, A. Yu. Petrov +1

In this paper, we study in detail various solutions, especially kink ones, in different nonlocal scalar field theories, whose kinetic term is described by an arbitrary non-polynomi…

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…
