                  "Meissner effect for black holes"


                címmel tartandó szemináriumára.


Kivonat:

It was shown long time ago that the extremal Kerr black hole exhibits a 
behaviour similar to the superconductors, namely, that it expels 
external magnetic (test) fields. This phenomenon was dubbed the Meissner 
effect. Since then, many particular examples have been found in which 
the Meissner effect operates. Most of these examples work with a 
particular black hole solution and a test magnetic field on given 
background, some results consider also the strong fields. In this talk 
we present a general proof that any extremal black hole (not necessarily 
Kerr, not necessarily asymptotically flat) with sufficient symmetries in 
fact expels external (weak or strong) magnetic and electric fields and, 
hence, that the Meissner effect is an inherent property of extremal 
black hole horizons.
