Migrating Carrollian particles on magnetized black hole horizons
arXiv:2302.11639 · doi:10.1103/PhysRevD.107.104014
Abstract
By considering a misaligned (asymptotically uniform) magnetic field in the background of a rotating black hole, we uncover a possibility for a highly non-trivial motion of Carrollian particles on the black hole horizon that is characterized by a time-dependent velocity field and reminds us (because of its latitudinal oscillations) of a 'monarch butterfly migration'.
