Exact Floquet quantum many-body scars under Rydberg blockade
Kaoru Mizuta, Kazuaki Takasan, Norio Kawakami
Abstract
The authors propose quantum many-body scars in periodically-driven systems in the presence of Rydberg blockade. While almost all states relax to infinite temperature states, the states in a subspace spanned by exact Floquet scar eigenstates completely avoid thermalization and show persistent oscillation in both microscopic and stroboscopic time
