摘要: Quantum many-body scarring is a recently discovered weak ergodicity-breaking phenomenon in quantum systems. It was first seen experiments with Rydberg atom array simulators, and characterized by nonthermalizing periodic revivals of certain initial-state configurations. Here, the authors extend our understanding physical origins this showing through an explicit construction that scars can arise presence entangled virtual degrees freedom undergoing dynamics. This demonstrates novel analytic scenario, whereby intrinsically states exhibit otherwise chaotic system, enriching phenomenology scarring.
