First law of entanglement entropy in AdS black hole backgrounds
The first law for entanglement entropy in CFT in an odd-dimensional asymptotically AdS black hole is studied by using the $\mathrm{AdS}/\mathrm{CFT}$ duality. The entropy of CFT considered here is due to the entanglement between two subsystems separated by the horizon of the AdS black hole, which itself is realized as …
