Horizon strings as 3D black hole microstates
Arjun Bagchi, Daniel Grumiller, M. M. Sheikh-Jabbari
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.
