Title: Exploring thermal CFTs

Abstract: In this talk, I will present recent developments in the study of Conformal Field Theories (CFTs) at finite temperature. The motivation of this work is different applications to holography, black holes in AdS as well as interesting statistical physics systems. After a short overview to the usual (zero Temperature) conformal bootstrap approach to CFTs, I will discuss how the dynamics at finite temperature are constrained by the Kubo-Martin-Schwinger (KMS) condition. I will present explicit sum rules for one-point functions, providing a basis for setting up a numerical bootstrap problem, the power of which I will demonstrate with specific examples. Furthermore, the KMS condition can be used to extract the leading behavior of one-point functions for heavy operators analytically. Lastly, I will show how to generalize this framework to temporal line-defects akin to Polyakov loops in gauge theories.

The talk will be based on 2306.12417, 2312.13030, 2407.14600 and 2411.00978
