TL;DR

This paper explores the fate of small Schwarzschild blackholes in AdS_5×S^5 using gauge theory and AdS/CFT, revealing a smooth crossover replacing the phase transition and implications for blackhole singularities.

Contribution

It introduces a double scaling limit to resolve the blackhole-string transition singularity, showing a smooth crossover in the gauge theory.

Findings

Phase transition becomes a smooth crossover

Multiply wound Polyakov lines condense at crossover

Density of states remains smooth during transition

Abstract

In this talk we discuss the fate of the small Schwarzschild blackhole of $AdS_5\times S^5$ using the AdS/CFT correspondence at finite temperature. The third order $N = \infty$ phase transition in the gauge theory corresponds to the blackhole-string transition. This singularity is resolved using a double scaling limit in the transition region. The phase transition becomes a smooth crossover where multiply wound Polyakov lines condense. In particular the density of states is also smooth at the crossover. We discuss the implications of our results for the singularity of the Lorenztian section of the small Schwarzschild blackhole.
