@inproceedings{Varikuti2022OutoftimeOC, title={Out-of-time ordered correlators in kicked coupled tops and the role of conserved quantities in information scrambling}, author={Naga Dileep Varikuti and Vaibhav Madhok}, year={2022} }

We investigate the operator growth dynamics in a bipartite system of kicked coupled tops with out-of-time ordered correlators (OTOC). We numerically study OTOCs for different types of initial operators, including the case of random operators where the operators are chosen randomly from the Gaussian unitary ensemble. We observe that the presence of a conserved quantity results in different types of scrambling behaviors for various choices of initial operators depending on whether the operators…

It is shown that this bipartite OTOC is equal to the operator entanglement of the evolution, and its interplay with entangling power is determined, and it is provided operational significance by unraveling intimate connections with average entropy production and scrambling of information at the level of quantum channels.
