Black hole hair removal: non-linear analysis

Black Hole Hair Removal: Non-linear Analysis

BMPV black holes in flat transverse space and in Taub-NUT space have identical near horizon geometries but different microscopic degeneracies. It has been proposed that this difference can be accounted for by different contribution to the degeneracies of these black holes from hair modes, – degrees of freedom living outside the horizon. In this paper we explicitly construct the hair modes of th...

Non-Linear Invariance of Black Hole Entropy

Thermal Hair of Quantum Black Hole

We investigate the possibility of statistical explanation of the black hole entropy by counting quasi-bounded modes of thermal fluctuation in two dimensional black hole spacetime. The black hole concerned is quantum in the sense that it is in thermal equilibrium with its Hawking radiation. It is shown that the fluctuation around such a black hole obeys a wave equation with a potential whose pea...

Black Hole Hair: Twenty{{ve Years After

Originally regarded as forbidden, black hole \hair" are elds associated with a stationary black hole apart from the gravitational and electromagnetic ones. Several stable stationary black hole solutions with gauge or Skyrme eld hair are known today within general relativity. We formulate here a \no scalar{ hair" conjecture, and adduce some new theorems that almost establish it by ruling out-for...

Three Charge Supertubes and Black Hole Hair

We construct finite size, supersymmetric, tubular D-brane configurations with three charges, two angular momenta and several brane dipole moments. In type IIA string theory these are tubular configurations with D0, D4 and F1 charge, as well as D2, D6 and NS5 dipole moments. These multi-charge generalizations of supertubes might have interesting consequences for the physics of the D1-D5-P black ...
