Krylov complexity in saddle-dominated scrambling
A bstract In semi-classical systems, the exponential growth of the out-of-time-order correlator
(OTOC) is believed to be the hallmark of quantum chaos. However, on several occasions, it …

Does scrambling equal chaos?
Focusing on semiclassical systems, we show that the parametrically long exponential
growth of out-of-time order correlators (OTOCs), also known as scrambling, does not …
