Towards the web of quantum chaos diagnostics
Abstract We study the connections between three quantities that can EMPTY VEG CAPS "00" be used as diagnostics for quantum chaos, i.e., the out-of-time-order correlator (OTOC), Loschmidt echo (LE), and complexity.We generalize the connection between OTOC and LE for infinite dimensions and extend it for higher-order OTOCs and Headband multi-fold LEs
