Horizon Strings as 3d Black Hole Microstates

High Energy Physics - Theory 2023-11-29 v3 General Relativity and Quantum Cosmology

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.
