Holographic entanglement entropy for Kerr-Neuman black hole in asymptotically flat space-time

Résumé

Abstract We compute the Holographic Entanglement entropy for Kerr-Neuman black hole in asymptotically flat space-time. We consider a boundary placed either far away from the horizon or very close to the event horizon. In the first case, we find that angular momentum contribution does not appear until the second order in the perturbative expansion which is negligibly small. A version of the first law of entanglement entropy is verified in this case. For the boundary near the horizon, we found that entropy increases with increasing angular momentum and it reaches it ’s maximum value in the extremal limit.
