Τίτλος: Analytic tools for thermal holographic correlators (and not only)

Περίληψη: Finite-temperature systems have always played a central role in physics. In recent years, the study of conformal field theories in a thermal state has gained momentum, with applications ranging from condensed matter to black holes through the AdS/CFT correspondence. In this talk, I will introduce a general analytic bootstrap framework for thermal two-point functions, explaining how to decompose them in terms of generalized free field correlators. I will then apply this framework to holographic CFTs at leading order in large N, focusing in particular on thermal scalar two-point functions. I will address the specific challenges arising from considering scalars with integer dimensions, and I will show how these tools are able to produce a prediction that is not only consistent with previous studies of scalars with half-integer dimensions, but also in agreement with the numerical solution of the wavefunction in the bulk.

This talk is based on the works hep-th/2506.06422 and hep-th/2510.20894.
