Renyi entropies of a black hole from Hawking radiation
arXiv:0801.4645 · doi:10.1209/0295-5075/83/60009
Abstract
Renyi entropies of a black hole are evaluated by counting the states of the Hawking radiation which fills a thin shell surrounding the horizon. The width of the shell is determined from its energy content and the corresponding mass defect. The Bekenstein-Hawking formula for the entropy of the black hole is correctly reproduced.
