Shadow structure of generalized black-bounce metrics
Jose R. Nascimento, Ana R. M. Oliveira, Albert Yu. Petrov +2
The existence of black hole shadows is one of the most interesting effects of the strong field regime of general relativity (GR). Recent observations by the Event Horizon Telescope…
Higher-order Chern-Simons extensions to QED in dimensions
Ricardo Avila, Albert Yu. Petrov, Carlos M. Reyes +2
In this work, we investigate radiative corrections in the higher-order extension of the Maxwell-Chern-Simons model coupled to standard spinor matter in dimensions. We begin a…
Fermionic greybody factors and strong gravitational lensing by Lorentz-violating global monopole
F. M. Belchior, R. V. Maluf, A. R. M. Oliveira +2
In this work, we study the greybody factors (GFs) of spin 1/2 and spin 3/2 fermions for a black hole with global monopole in self-interacting Kalb-Ramond gravity with Lorentz symme…
Gravitational lensing by generalized black-bounce space-times
C. Furtado, A. L. A. Moreira, J. R. Nascimento +2
We study gravitational lensing by generalized black-bounce space-times both in regimes of weak and strong field approximations. These metrics interpolate between regular blac…
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 theor…
Geometrical deformation of brane matter field within gravity
Fernando M. Belchior, Roberto V. Maluf, Albert Yu. Petrov +1
In the context of braneworld scenarios, the real scalar field plays a crucial role by providing thickness for brane. In this work, we investigate a codimension-one thick brane with…
Nonlinear -models in the Eddington-inspired Born-Infeld Gravity
J. R. Nascimento, Gonzalo J. Olmo, P. J. Porfírio +2
In this paper we consider two different nonlinear -models minimally coupled to Eddington-inspired Born-Infeld gravity. We show that the resultant geometries represent minimal mo…
Quantum superfield supersymmetry
A. Yu. Petrov
This paper is a collection of lecture notes on the superfield approach in three- and four-dimensional supersymmetric quantum field theory. Many examples of the applications of this…
