Towards the web of quantum chaos diagnostics
Abstract We study the connections between three quantities that can be used as diagnostics for quantum chaos, i.e., the out-of-time-order correlator 1800 tequila lafc (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 multi-fold LEs.Novel appl
