SUMMARY:Quasi-normal modes and fermionic vacuum decay around a Kerr black 
 hole  - Peter Millington (University of Nottingham)

DESCRIPTION:The non-rotating fermion vacuum in Kerr spacetimes is unstable
  to a spontaneous vacuum decay\, which leads to the formation of a co-rota
 ting Dirac sea. This decay\, which amounts to the fermionic pendant of the
  black hole bomb instability\, has an analogue in the electrodynamics of s
 upercritical fields\, and we show that the decay process is encoded by the
  set of quasi-normal fermion modes.
