Supersymmetric Dyons, Superstrings, and Rotating Wormholes
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 ...

Weak cosmic censorship in Born–Infeld electrodynamics and bound on charge-to-mass ratio
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 ...

Born-Infeld gravity coupled to Born-Infeld electrodynamics [PDF]
We investigate spherically symmetric, static spacetimes in Eddington-inspired Born-Infeld gravity coupled to Born-Infeld electrodynamics. The two constants, $b^2$ and $ $ which parametrise the Born-Infeld structures in the electrodynamics (matter) and gravity sectors, characterise the features of our analytical solutions.

THE CONVERGENCE OF SCIENCE AND RELIGION
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
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
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,

All-multiplicity one-loop amplitudes in Born-Infeld electrodynamics from generalized unitarity
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 ...

On Current-Squared Flows and ModMax Theories
We show that the recently introduced ModMax theory of electrodynamics and its Born-Infeld-like generalization are related by a flow equation driven by a quadratic combination of stress-energy tensors.

We encode dynamical symmetries of Born-Infeld theory in a geometry on the tangent bundle of generally curved spacetime manifolds. The resulting covariant formulation of a maximal acceleration extension of special and general relativity is put to use in the discussion of particular point particle dynamics and the transition to a first quantized theory.
