Mixed State Deep Thermalization under Generic Quantum Errors
Xie-Hang Yu, Pavel Kos
Pure-state deep thermalization predicts that, after sufficient scrambling, projected ensembles approach universal distributions that contain information beyond the reduced density…

Magnetic domains stabilized by symmetry-protected zero modes
Pavel Kos, Dominik S. Wild, Kristian Knakkergaard Nielsen
Understanding mechanisms for the breakdown of thermalization in closed quantum systems is a central problem in quantum many-body physics. We demonstrate strong nonergodic behavior…
