Phys. Rev. D 59, 081501(R) (1999) [5 pages]Entropy of 2D black holes from counting microstates
We present a microscopical derivation of the entropy of the black hole solutions of the Jackiw-Teitelboim theory. We show that the asymptotic symmetry of two-dimensional (2D) anti–de Sitter space is generated by a central extension of the Virasoro algebra. Using a canonical realization of this symmetry and Cardy’s formula we calculate the statistical entropy of 2D black holes, which turns out to agree, up to a factor √2, with the thermodynamical result. © 1999 The American Physical Society URL:
