Abstract

In this work, we present the Simpson-Visser black-bounce (SV-BB) spacetime with both electric and magnetic charges (the dyonic SV-BB) as an exact solution of general relativity coupled to Maxwell electrodynamics and an anisotropic fluid with vanishing radial pressure. We assume the anisotropic fluid represents an Einstein cluster, which consists of a dense system of particles moving in circular orbits that generate only tangential pressure and zero radial pressure. We show that the dyonic SV-BB metric, which provides a regular black hole spacetime, can be obtained as an exact solution to the Einstein field equations sourced by a combination of an Einstein cluster (which is responsible for providing the exotic matter required to keep a black-bounce throat open) and an electromagnetic field in the framework of Maxwell electrodynamics.

A Temporal Splitting Theorem for Chronological Spaces

We obtain a generalization of Geroch's Theorem on temporal foliations in a globally hyperbolic space-time to chronological spaces under suitable topological and order-theoretic requirements. The foliation can be chosen to contain a given relatively compact antichain in one slice. We first prove the corresponding extension result for countable causal sets, and then give a direct proof for chronological spaces using past sets. Furthermore, we show that any chronological space-time admits a generalized Cauchy hypersurface containing a prescribed compact achronal set: it is crossed once by every inextendible timelike curve which is also a maximal chronological chain.

Matter-Dark Energy Transition: A Dynamical Systems Approach

In this study, we deviate from the traditional examination of the evolving universe through the scale factor and instead consider a parameter $\chiME$, defined by the ratio of two competing energy densities: matter (DM) and dynamic dark energy (DDE). While the scale factor's role is not neglected, it is inherently embedded within the evolution equations of these competing energy densities. By employing dynamical systems techniques, we investigate the behaviour of this ratio $\chiME$ to understand the dynamics surrounding the cosmological transition from matter domination to dark energy domination. This methodological shift allows for a more nuanced analysis of the matter-to-dark energy transition.

Enhancement of Electromagnetic Memory Effects

We show that the amplitude of electromagnetic memory can be significantly enhanced in comparison to known estimates. In a Lorentz breaking phase of lowered phase velocity of light, there exist critical spacetime directions of memory-source emission along the effective light cone, about which the total memory offset receives order of magnitude increases. The same amplification is already present in the Lorentz preserving case by considering ultra-relativistic memory-source charges. These observations may pave the way for a first observation of the phenomenon of memory and laboratory tests of the concepts of asymptotic symmetries and soft theorems.
