英文摘要:
In [1] the horizon fluffs proposal is put forward to identify microstates of generic nonextremal three-dimensional Banados-Teitelboim-Zanelli (BTZ) black holes. The proposal is that black hole microstates, the horizon fluffs, are certain near horizon soft hairs which are not in the coadjoint orbits of the asymptotic Virasoro algebra associated with the BTZ black holes. It is also known that AdS(3) Einstein gravity has more general black hole solutions than the BTZ family which are generically described by two periodic, but otherwise arbitrary, holomorphic and antiholomorphic functions. We show that these general AdS(3) black holes which are typically conformal descendants of the BTZ black holes and are characterized by the associated Virasoro coadjoint orbits, appear as coherent states in the asymptotic symmetry algebra corresponding to the black hole family. We apply the horizon fluffs proposal to these generic AdS(3) black holes and identify the corresponding microstates. We then perform microstate counting and compute the entropy. The entropy appears to be an orbit invariant quantity, providing an important check for the horizon fluffs proposal.
