Abstract:
Low-energy, near-horizon scaling limits of black holes which lead to string theory on AdS_2 x S^2 are described. Unlike the higher-dimensional cases, in the simplest approach all finite-energy excitations of AdS_2 x S^2 are suppressed. Surviving zero-energy configurations are described. These can include tree-like structures in which the AdS_2 x S^2 throat branches as the horizon is approached, as well as disconnected AdS_2 x S^2 universes. In principle, the black hole entropy counts the quantum ground states on the moduli space of such configurations. In a nonsupersymmetric context AdS_D for general D can be unstable against instanton-mediated fragmentation into disconnected universes. Several examples are given.- space-time: anti-de Sitter
- space-time: sphere
- fragmentation
- black hole: pair
- field theory: conformal
- scaling
- string model
- instanton
