One-Loop Corrections to Near-Extremal Kerr Thermodynamics from Semiclassical Virasoro Blocks

We propose a method to perform an exact calculation of one-loop quantum corrections to black hole entropy in terms of Virasoro semiclassical blocks. We analyze in detail a four-dimensional Kerr black hole and show that in the near-extremal limit a branch of long-lived modes arises. We prove that the... View More
