recommendations! Published in 2024 at "Journal of High Energy Physics"

DOI: 10.1007/jhep06(2024)191

Abstract: For the general theory of nonlinear electrodynamics (NLED) we prove that causality implies both the Dominant Energy Condition (DEC) and, surprisingly, the Strong Energy Condition (SEC). This has implications for gravitational applications, such as regular… read more here.

DOI: 10.1016/j.aop.2022.168880

Abstract: The first exact rotating charged black hole solution to the Einstein–nonlinear electrodynamics theory is reported. It is equipped with mass, rotation parameter, electric and magnetic charges, and three parameters due to the electrodynamics: β is… read more here.

DOI: 10.1088/1361-6382/ad756b

Abstract: We demonstrate the existence of photon traps within the framework of nonlinear electrodynamics. The trapping mechanism is based on the fact that, for null background fields, the optical metric reduces to the Kerr–Schild form, which… read more here.

DOI: 10.1103/physrevd.100.125008

Abstract: Bekenstein's inequality sets a bound on the entropy of a charged macroscopic body. Such a bound is understood as a universal relation between physical quantities and fundamental constants of nature that should be valid for… read more here.

DOI: 10.1103/physrevd.102.104033

Abstract: Along the last decades, several regular black hole (BH) solutions, i.e., singularity-free BHs, have been proposed and associated to nonlinear electrodynamics models minimally coupled to general relativity. Within this context, it is of interest to… read more here.

DOI: 10.1103/physrevd.105.024021

Abstract: It is shown here that symmetric hyperbolicity, which guarantees well-posedness, leads to a set of two inequalities for matrices whose elements are determined by a given theory. As a part of the calculation, carried out… read more here.

Abstract: We have investigated the polarized images of synchrotron emission from magnetically charged, spherically symmetric regular Bronnikov black hole (in general relativity coupled to nonlinear electrodynamics) and the singular Reissner-Nordstr\"{o}m black hole (in general relativity coupled… read more here.

DOI: 10.1103/physrevd.95.025011

Abstract: Huge electromagnetic fields are known to be present during the late stages of the dynamics of supernovae. Thus, when dealing with electrodynamics in this context, the possibility may arise to probe nonlinear theories (generalizations of… read more here.

DOI: 10.1103/physrevlett.127.271601

Abstract: We construct a Lagrangian for general nonlinear electrodynamics that features electric and magnetic potentials on equal footing. In the language of this Lagrangian, discrete and continuous electric-magnetic duality symmetries can be straightforwardly imposed, leading to… read more here.
