# Hawking radiation energy and entropy from a Bianchi-Smerlak semiclassical black hole

@article{Abdolrahimi2015HawkingRE, title={Hawking radiation energy and entropy from a Bianchi-Smerlak semiclassical black hole}, author={Shohreh Abdolrahimi and Don N Page}, journal={Physical Review D}, year={2015}, volume={92}, pages={083005} }

Eugenio Bianchi and Matteo Smerlak have found a relationship between the Hawking radiation energy and von Neumann entropy in a conformal field emitted by a semiclassical two-dimensional black hole. We compare this relationship with what might be expected for unitary evolution of a quantum black hole in four and higher dimensions. If one neglects the expected increase in the radiation entropy over the decrease in the black hole Bekenstein-Hawking $A/4$ entropy that arises from the scattering of…

The result shows that the thermodynamics properties of the black hole are greatly influenced by the GUP, and GUP-corrected entropy is higher than the original entropy.

### Typical entanglement entropy in the presence of a center: Page curve and its variance

- Physics, Computer SciencePhysical Review D
- 2019

It is shown that for large systems the variance is small, $\Delta S_A/\langle{S_{A}}\rangle\ll 1$, and therefore the average entanglement entropy is typical and the exact formula for the average entropy and its variance in the presence of a center is presented.

For a system of non-interacting spins in a magnetic field, the thermal entropy arises as the typical entanglement entropy of a subsystem as well as the application to physical systems in an energy eigenstate.
