Titre | Hydrodynamic Tails in CFT and the Large Dimension Expansion |
Résumé | The late time physics of interacting Quantum Field Theories at finite temperature is controlled by hydrodynamics. For CFTs this implies that heavy operators -- which are generically expected to create thermal states -- can be studied semi-classically. I will show that hydrodynamic loops universally fix the OPE coefficients C_{HH'L}, on average, of all neutral light operators with two non-identical heavy ones, as a function of the scaling dimension and spin of the operators. These methods can be straightforwardly extended to CFTs with global symmetries, and generalize recent EFT results on large charge operators away from the case of minimal dimension at fixed charge. |
