SUMMARY:The Conformal Bootstrap at Finite Temperature and the 3d Ising CFT
DESCRIPTION:Featuring Murat Kologlu\, Caltech\n\nPart of the HET Seminar Se
ries.\n\nMany properties of conformal field theories (CFTs) have been uncov
ered by the conformal bootstrap in the past decade. The focus has mostly be
en on bootstrapping flat-space four-point functions for the local data: spe
ctra and OPE coefficients. Can we extend the bootstrap program to CFTs on n
ontrivial manifolds? Recently\, we took the first step in this direction by
studying CFTs on a Euclidean circle times flat space\, corresponding to pu
tting the Lorentzian CFT at finite temperature. I will explain how to boots
trap thermal CFT two-point functions to solve for the thermal averages of l
ocal operators. I will describe analytic techniques such as the "thermal Lo
rentzian inversion formula" and a large-spin perturbation theory for the th
ermal data. Finally\, I will apply these techniques to approximately solve
the thermal bootstrap for the 3d Ising CFT and obtain predictions for the t
hermal averages of infinitely many operators\, including a prediction for t
he free energy density.
