Quantifying operator spreading and chaos in Krylov subspaces with quantum state reconstruction
Abinash Sahu, Naga Dileep Varikuti, Bishal Kumar Das +1
We study operator spreading in many-body quantum systems by its potential to generate an informationally complete measurement record in quantum tomography. We adopt continuous weak…

Probing Dynamical Sensitivity of a Non-KAM System Through Out-of-Time-Order Correlators
Naga Dileep Varikuti, Abinash Sahu, Arul Lakshminarayan +1
Non-KAM (Kolmogorov-Arnold-Moser) systems, when perturbed by weak time-dependent fields, offer a fast route to classical chaos through an abrupt breaking of invariant phase space t…
