Quasi-normal modes and fermionic vacuum decay around a Kerr black hole

Coutant, Antonin; Millington, Peter

Abstract

We analyze the instability of the non-rotating fermion vacuum in Kerr spacetimes. We describe how the co-rotating Fermi sea is formed as a result of a spontaneous vacuum decay. Most significantly, and drawing upon intuition gained from analogous electrodynamic processes in supercritical fields, we show that this decay process is encoded entirely in the set of quasi-normal fermion modes.
