Weak cosmic censorship in Born–Infeld electrodynamics and bound on charge-to-mass ratio
European Physical Journal C: Particles and Fields, 2020 We construct a class of counterexamples to cosmic censorship in four dimensional Einstein–Born–Infeld theory with asymptotically anti-de Sitter boundary conditions, and investigate the effect of the Born–Infeld parameter b in comparison with the ...

Entropy bound in Einstein-Born-Infeld black holes [PDF]
Physical Review D, 2021 We study the validity of Bekenstein's entropy bound for a charged black hole in the context of nonlinear electrodynamics. Bekenstein's inequalities are commonly understood as universal relations between the entropy, the charge, the momentum and the ...

Supersymmetric Dyons, Superstrings, and Rotating Wormholes
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 We construct supersymmetric dyon solutions based on the ‘t Hooft/Polyakov monopole. We show that these solutions satisfy κ‐symmetry constraints and can therefore be generalized to supersymmetric solutions of type I SO(32) string theory. After applying a T‐duality transformation to these solutions, we obtain two D3‐branes connected by a wormhole ...

Supersymmetric born-infeld lagrangians [PDF]
Physics Letters B, 1987 Abstract The supersymmetric completion of four-dimensional Born-Infeld-type actions is established by means of superspace techniques for the construction of higher-curvature invariants. The coupling of these actions to supergravity is also obtained. These results are relevant for the understanding of the full effective action of superstring theories.

THE CONVERGENCE OF SCIENCE AND RELIGION
Zygon®, Volume 56, Issue 4, Page 1008-1026, December 2021., 2021 Abstract Many natural patterns are obvious. We observe them in the weather, our physiology, the solar system, and our habits. We see that every finite thing is made up of parts and every finite thing is a part of something else. Relationships and characteristics occur in patterns.

Double Copy from Homotopy Algebras
Fortschritte der Physik, Volume 69, Issue 8-9, September 2021., 2021 It will be shown that the BRST Lagrangian double copy construction of N = 0 supergravity as the ‘square’ of Yang–Mills theory finds a natural interpretation in terms of homotopy algebras. The authors significantly expand on their previous work arguing the validity of the double copy at the loop level, and they give a detailed derivation of the double ...

Gravitational Collapse and Singularity Removal in Rastall Theory
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 In the present work, we study spherically symmetric gravitational collapse of a homogeneous fluid in the framework of Rastall gravity. Considering a nonlinear equation of state (EoS) for the fluid profiles, we search for a class of nonsingular collapse solutions and the possibility of singularity removal. We find that depending on the model parameters,

On the Schrödinger–Born–Infeld System [PDF]
Bulletin of the Brazilian Mathematical Society, New Series, 2018 In this paper we study a system which we propose as a model to describe the interaction between matter and electromagnetic field from a dualistic point of view. This system arises from a suitable coupling of the Schrödinger and the Born-Infeld lagrangians, this latter replacing the role that, classically, is played by the Maxwell lagrangian.

All-multiplicity one-loop amplitudes in Born-Infeld electrodynamics from generalized unitarity
Journal of High Energy Physics, 2020 We initiate a study of non-supersymmetric Born-Infeld electrodynamics in 4d at the quantum level. Explicit all-multiplicity expressions are calculated for the purely rational one-loop amplitudes in the self-dual (+ + … +) and next-to-self-dual ...
