Black Holes with Flavors of Quantum Hair?
msra(2006)
摘要
We show that black holes can posses a long-range quantum hair of
super-massive tensor fields, which can be detected by Aharonov-Bohm tabletop
interference experiments, in which a quantum-hairy black hole, or a remnant
particle, passes through the loop of a magnetic solenoid. The long distance
effect does not decouple for an arbitrarily high mass of the hair-providing
field. Because Kaluza-Klein and String theories contain infinite number of
massive tensor fields, we study black holes with quantum Kaluza-Klein hair. We
show that in five dimensions such a black hole can be interpreted as a string
of `combed' generalized magnetic monopoles, with their fluxes confined along
it. For the compactification on a translation-invariant circle, this
substructure uncovers hidden flux conservation and quantization of the monopole
charges, which constrain the quantum hair of the resulting four-dimensional
black hole. For the spin-2 quantum hair this result is somewhat unexpected,
since the constituent `magnetic' charges have no `electric' counterparts.
Nevertheless, the information about their quantization is encoded in
singularity.
