Corotating binary systems of identical Kerr-Newman black holes
Physics Letters B, 2020 In the present paper binary configurations of identical corotating Kerr-Newman black holes separated by a massless strut are derived and studied. After solving the axis conditions and establishing the absence of magnetic charges in the solution, one gets

Advanced Functional Materials, EarlyView.Tin hexathiophosphate memristors leverage intrinsic nanopores together with a guided filament formation strategy to regulate titanium ion motion and switching behavior. The devices support reliable nonvolatile memory and reconfigurable logic‐in‐memory, demonstrating 14 Boolean logic functions in a single cell.

International Journal of Computer Applications, 2013 In this paper we adapt black holes optimization algorithms for binary search spaces by applying a sigmoid transformation to the gravity and electrical forces. Black holes algorithm is a Swarm Algorithm inspired of Black Holes for Optimization Problems.

Transient Black Hole Binaries [PDF]
, 2016 The last two decades have seen a great improvement in our understand- ing of the complex phenomenology observed in transient black-hole binary systems, especially thanks to the activity of the Rossi X-Ray Timing Explorer satellite, com- plemented by observations from many other X-ray observatories and ground-based radio, optical and infrared facilities.

AIP Conference Proceedings, 2008 Recent work at the interface between analytical and numerical relativity is deepening our understanding of the two‐body dynamics and of the gravitational radiation from binary black‐hole coalescences. In this talk we review the most recent advances, focusing on the transitions from inspiral to merger and to ringdown, and on the recoil velocity of the ...

Metric for two arbitrary Kerr sources
Physics Letters B, 2019 The full metric describing a stationary axisymmetric system of two arbitrary Kerr sources, black holes or hyperextreme objects, located on the symmetry axis and kept apart in equilibrium by a massless strut is presented in a concise explicit form ...

Charged and rotating multi-black holes in an external gravitational field
European Physical Journal C: Particles and Fields, 2022 We construct analytical and regular solutions in four-dimensional General Relativity which represent multi-black hole systems immersed in external gravitational field configurations.

Advanced Functional Materials, EarlyView.ABSTRACT In this work, we introduce a trifluoromethoxy (OCF3) group as a pseudo‐halogen terminal group design for non‐fullerene acceptors, which combines strong inductive electron‐withdrawing ability with moderate resonance donation. The as‐synthesized BTP‐OCF3, when benchmarked against its methoxy analogue BTP‐OCH3, demonstrates narrowed bandgap ...
