CHIRAL BLACK HOLE IN THREE-DIMENSIONAL GRAVITATIONAL CHERN-SIMONS

초록

A chiral black hole can be defined by the three-dimensional pure gravitational Chern-Simons action as an independent gravitational theory. The third-order derivative of the Cotton tensor gives a dimensional constant which plays a role of the cosmological constant. The handedness of angular momentum depends on the signature of the Chern-Simons coefficient. Even in the massless black hole which corresponds to the static black hole, it has a nonvanishing angular momentum. We also discuss three different entropies depending on the methods of Wald, Cardy and 't Hooft.
