Thermal out-of-time-order correlators, KMS relations, and spectral functions

Abstract We describe general features of thermal correlation functions in quantum systems, with specific focus on the fluctuation-dissipation type relations implied by the KMS condition. These end up relating correlation functions with different time ordering and thus should naturally be viewed in t...
