The study of open quantum systems often relies on approximate master equations derived
under the assumptions of weak coupling to the environment. However when the system is …

Interacting many-body quantum systems show a rich array of physical phenomena and
dynamical properties, but are notoriously difficult to study: they are analytically challenging …

Quantum Chaos has originally emerged as the field which studies how the properties of
classical chaotic systems arise in their quantum counterparts. The growing interest in …

A bstract The out-of-time-order correlator (OTOC) is considered as a measure of quantum
chaos. We formulate how to calculate the OTOC for quantum mechanics with a general …

In this tutorial, we present the definition, interpretation, and properties of some of the main
quasiprobabilities that can describe the statistics of measurement outcomes evaluated at …

We demonstrate analytically and verify numerically that the out-of-time order correlator is
given by the thermal average of Loschmidt echo signals. This provides a direct link between …

With the long-term goal of studying models of quantum gravity in the lab, we propose
holographic teleportation protocols that can be readily executed in table-top experiments …

Out-of-time ordered (OTO) correlation functions describe scrambling of information in
correlated quantum matter. They are of particular interest in incoherent quantum systems …

The out-of-time-ordered correlators (OTOC), a fundamental concept for quantifying quantum
information scrambling, has recently been suggested to be an order parameter to …
