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 fi…

Pulse shape optimization against Doppler shifts and delays in optical quantum communication
Emanuel Schlake, Roy Barzel, Dennis Rätzel +1
High relative velocities and large distances in space-based quantum communication with satellites in lower earth orbits can lead to significant Doppler shifts and delays of the sig…

Gaussian orbital perturbation theory in Schwarzschild space-time in terms of elliptic functions
Oleksii Yanchyshen, Claus Lämmerzahl
General relativistic Gauss equations for osculating elements for bound orbits under the influence of a perturbing force in an underlying Schwarzschild space-time have been derived…
