Spinning particles in general relativity: Momentum-velocity relation for the Mathisson-Pirani spin condition
L. Filipe O. Costa, Georgios Lukes-Gerakopoulos, Oldřich Semerák
The Mathisson-Papapetrou-Dixon (MPD) equations, providing the "pole-dipole" description of spinning test particles in general relativity, have to be supplemented by a condition spe…
Chaotic motion in the Johannsen-Psaltis spacetime
Ondřej Zelenka, Georgios Lukes-Gerakopoulos
The Johannsen-Psaltis spacetime is a perturbation of the Kerr spacetime designed to avoid pathologies like naked singularities and closed timelike curves. This spacetime depends no…
Time parameterizations and spin supplementary conditions of the Mathisson-Papapetrou-Dixon equations
Georgios Lukes-Gerakopoulos
The implications of two different time constraints on the Mathisson-Papapetrou-Dixon (MPD) equations are discussed under three spin supplementary conditions (SSC). For this reason…
Recurrence Analysis as a tool to study chaotic dynamics of extreme mass ratio inspiral in signal with noise
Georgios Lukes-Gerakopoulos, Ondřej Kopáček
Recurrence analysis is a well settled method allowing to discern chaos from order, and determinism from noise. We apply this tool to study time series representing geodesic and ins…
Spinning test-body orbiting around a Kerr black hole: circular dynamics and gravitational-wave fluxes
Georgios Lukes-Gerakopoulos, Enno Harms, Sebastiano Bernuzzi +1
In a recent work, [Phys. Rev. D. 94, 104010 (2016)], hereafter Paper I, we have numerically studied different prescriptions for the dynamics of a spinning particle in circular moti…
