Horizon Strings as 3d Black Hole Microstates
arXiv:2210.10794 · doi:10.21468/SciPostPhys.15.5.210
Abstract
We propose that 3d black holes are an ensemble of tensionless null string states. These microstates typically have non-zero winding. We evaluate their partition function in the limit of large excitation numbers and show that their combinatorics reproduces the Bekenstein-Hawking entropy and its semiclassical logarithmic corrections.
