Zusammenfassung:
Non-supersymmetric black hole microstates are of great interest in the
context of the black hole information paradox. We identify the holographic
description of the general class of non-supersymmetric orbifolded D1-D5-P
supergravity solutions found by Jejjala, Madden, Ross and Titchener. This class
includes both completely smooth solutions and solutions with conical defects,
and in the near-decoupling limit these solutions describe degrees of freedom in
the cap region. The CFT description involves a general class of states obtained
by fractional spectral flow in both left-moving and right-moving sectors,
generalizing previous work which studied special cases in this class. We
compute the massless scalar emission spectrum and emission rates in both
gravity and CFT and find perfect agreement, thereby providing strong evidence
for our proposed identification. We also investigate the physics of ergoregion
emission as pair creation for these orbifolded solutions. Our results represent
the largest class of non-supersymmetric black hole microstate geometries with
identified CFT duals presently known.
