Dynamical crossover behavior in the relaxation of quenched quantum many-body systems

AA Makki, S Bandyopadhyay, S Maity, A Dutta - Physical Review B, 2022 - APS
A crossover between different power-law relaxation behaviors of many-body periodically
driven integrable systems has come to light in recent years. We demonstrate, using …

Late-time critical behavior of local stringlike observables under quantum quenches

S Bandyopadhyay, A Polkovnikov, A Dutta - Physical Review B, 2023 - APS
In recent times it has been observed that signatures of equilibrium quantum criticality
surprisingly show up in many-body systems, which are manifestly far from equilibrium. We …
