Point particles on the string in a three-dimensional AdS universe
Petr Lukeš, Pavel Krtouš
BTZ spacetime is a long-known locally AdS solution to the Einstein equations in 1 timelike and 2 spacelike dimensions. Its static variant is interpreted as a black hole whose mass…
Higher-dimensional black holes with multiple equal rotations
Eliška Polášková, Pavel Krtouš
We study a limit of the Kerr-(A)dS spacetime in a general dimension where an arbitrary number of its rotational parameters is set equal. The resulting metric after the limit formal…
Duality and -separability of Maxwell equations in Kerr-NUT-(A)dS spacetime
Valeri P. Frolov, Pavel Krtouš
We study properties of a recently proposed new ansatz for separation of variables in the Maxwell equations in four dimensional Kerr-NUT-(A)dS spacetime. We demonstrate that a dual…
Separation of variables in Maxwell equations in Plebanski-Demianski spacetime
Valeri P. Frolov, Pavel Krtouš, David Kubizňák
A new method for separating variables in Maxwell's equations in four- and higher-dimensional Kerr-(A)dS spacetimes proposed recently by Lunin is generalized to any off-shell metric…
The gyraton solutions on generalized Melvin universe with cosmological constant
Hedvika Kadlecová, Pavel Krtouš
We present and analyze new exact gyraton solutions of algebraic type II on generalized Melvin universe of type D which admit non-vanishing cosmological constant . We show that i…
Particle Interpretations and Green Functions for a Free Scalar Field
Pavel Krtouš
The formalism of Ashtekar and Magnon \cite{AshtekarMagnon:1975} for the definition of particles in quantum field theory in curved spacetime is further developed. The relation betwe…
