Title: Resumming non-linear effects in OTOC

Abstract: I will give an introduction to the out-of-time-order correlators (OTOCs), which characterize quantum chaos in a way comparable to the classical picture of divergent trajectories. For many-body systems with all-to-all interactions such as the SYK model, I will show a general expression for the OTOC that includes the non-linear effects.
