Non-minimal matter sector couplings in Lorentz-violating gravity: Self-consistent traversable wormholes and quasinormal modes
Renan B. Magalhães, Leandro A. Lessa, Rodolfo Casana
The anisotropies induced by Lorentz-violating fields pose significant challenges for the search for compact objects in non-vacuum environments. In this work, nevertheless, we demon…
Tight bounds on the Maxwell-Carroll-Field-Jackiw parameters using Fast Radio Bursts
Filipe S. Ribeiro, Pedro D. S. Silva, Rodolfo Casana +1
We investigate the arrival time and the Faraday rotation of extragalactic electromagnetic signals from fast radio bursts (FRBs) propagating through chiral cosmic media within the f…
Hypothesis of a bi-isotropic-like plasma permeating the interstellar space
Filipe S. Ribeiro, Pedro D. S. Silva, Rodolfo Casana +1
In this work, we study the propagation of electromagnetic waves in a magnetized chiral plasma that pervades the interstellar space. The Maxwell equations, supplemented by bi-isotro…
Self-dual compactons in the gauged restricted baby Skyrme model in the presence of an external magnetic field
N. H. Gonzalez-Gutierrez, Rodolfo Casana, André C. Santos
We investigate the existence of compact self-dual solitons in the restricted gauged baby Skyrme model in the presence of an external magnetic field. The consistent implementation o…
