Black Hole Entropy as Causal Links | | Djamel Dou
; Rafael D. Sorkin

3 Feb 2003 | | Journal: | Found.Phys. 33 (2003) 279-296 | | Subject: | gr-qc hep-th | | Affiliation: | University Center of Eloued), Rafael D. Sorkin (Syracuse University | | Abstract: | We model a black hole spacetime as a causal set and count, with a certain definition, the number of causal links crossing the horizon in proximity to a spacelike or null hypersurface $Sigma$. We find that this number is proportional to the horizon’s area on $Sigma $, thus supporting the interpretation of the links as the ``horizon atoms’’ that account for its entropy. The cases studied include not only equilibrium black holes but ones far from equilibrium. | | Source: | arXiv, gr-qc/0302009 | | Other source: | [GID 1043364] gr-qc/0302009 | | Services: | Forum | Review | PDF | Favorites | |
