Corrected entropy of the rotating black hole solution of the new massive gravity using the tunneling method and Cardy formula
We study the AdS rotating black hole solution for the
Bergshoeff-Hohm-Townsend (BHT) massive gravity in three dimensions. The field
equations of the asymptotically AdS black hole of the static metric can be
expressed as the first law of thermodynamics, i.e. . The corrected
Hawking-like temperature and entropy of asymptotically AdS rotating black hole
are calculated using the Cardy formula and the tunneling method. Comparison of
these methods will help identify the unknown leading correction parameter
in the tunneling method.Comment: 6 page
Non-Abelian Aharonov-Bohm effect with the time-dependent gauge fields
We investigate the non-Abelian Aharonov-Bohm (AB) effect for time-dependent
gauge fields. We prove that the non-Abelian AB phase shift related to
time-dependent gauge fields, in which the electric and magnetic fields are
written in the adjoint representation of generators, vanishes up to the
first order expansion of the phase factor. Therefore, the flux quantization in
a superconductor ring does not appear in the time-dependent Abelian or
non-Abelian AB effect.Comment: 4 page
