Nonlinear electrodynamics in Kerr-Newman-NUT- spacetime: exact solutions, horizons, and energy conditions
Oscar Galindo-Uriarte, Nora Breton, Claus Lämmerzahl +1
We construct two exact nonlinear-electrodynamic generalizations of the Kerr-Newman-NUT- spacetime. Imposing alignment between the principal directions of the electromagnetic fie…
General orbital perturbation theory in Schwarzschild space-time
Oleksii Yanchyshen, Eva Hackmann, Claus Lämmerzahl
We derive general relativistic Gaussian equations for osculating elements for orbits under the influence of a perturbing force without any restrictions in an underlying Schwarzschi…
Frequency shifts due to relativistic effects and retardation in continuous variable quantum key distribution
Emanuel Schlake, Jan P. Hackstein, Roy Barzel +3
Space-based quantum communication naturally involves satellites and ground stations exchanging optical signals at high altitudes and large relative velocities. Starting from genera…
Equilibrium models of Weyssenhoff spin fluid accretion tori around Kerr black holes
Sergio Gimeno-Soler, Sayantani Lahiri, Claus Lämmerzahl
The construction of equilibrium models of accretion disks around compact objects has become a highly relevant topic in the recent times, thanks to the current understanding that in…
General Relativity and Geodesy
Eva Hackmann, Moritz Huckfeldt, Claus Lämmerzahl +2
Mass redistribution on Earth due to dynamic processes such as ice melting and sea level rise leads to a changing gravitational field, observable by geodetic techniques. Monitoring…
The scalar angular Teukolsky equation and its solution for the Taub-NUT spacetime
Felix Willenborg, Dennis Philipp, Claus Lämmerzahl
The Taub-NUT spacetime offers many curious insights into the solutions of Einstein's electrovacuum equation. In the Bonnor interpretation, this spacetime possesses so-called Misner…
