Vaidya-Type Solutions of Quasitopological Gravity Interacting with Nonlinear Electrodynamics
Valeri P. Frolov, Chul-Moon Yoo, Andrei Zelnikov
We construct Vaidya-type solutions of quasitopological gravity coupled to nonlinear electrodynamics in arbitrary spacetime dimensions. Starting from the corresponding static spheri…
Regular Black Holes in Quasitopological Gravity: Null Shells and Mass Inflation
Valeri P. Frolov, Andrei Zelnikov
We investigate the phenomenon of mass inflation in the interior of regular black holes arising in quasitopological gravity (QTG). These geometries are characterized by a bounded cu…
Thomas precession, relativistic torque, and non-planar orbits
Andrzej Czarnecki, Andrei Zelnikov
We analyze the angular momentum balance for a particle undergoing Thomas precession. The relationships among relativistic torque, the center of mass, and the center of inertia for…
Regular black holes inspired by quasi-topological gravity
Valeri P. Frolov, Alex Koek, Jose Pinedo Soto +1
Recently it was demonstrated that by adding to the Einstein-Hilbert action a series in powers of the curvature invariants with specially chosen coefficients one can obtain a theory…
Ring wormholes and time machines
Valeri P. Frolov, Pavel Krtous, Andrei Zelnikov
In the present paper we discuss properties of a model of a ring wormhole, recently proposed by Gibbons and Volkov. Such a wormhole connects two flat spacetimes which are glued thro…
Chiral anomalies in black hole spacetimes
Valeri P. Frolov, Alex Koek, Jose Pinedo Soto +1
We study the properties of chiral anomalies in a wide class of spacetimes which possess a principal Killing-Yano tensor. This class includes metrics of charged rotating black holes…
