QMBSs are non-thermal highly excited eigenstates that coexist with typical eigenstates in the spectrum of many-body Hamiltonians, and have since been reported in multiple theoretical models, including the so-called PXP model, approximately realized by Rydberg simulators. At the same time, questions of how common QMBSs are and in what models they are physically realized remain open. In this Letter, we demonstrate that QMBSs exist in a broader family of models that includes and generalizes PXP to longer-range constraints and states with different periodicity. We show that in each model, multiple QMBS families can be found. Each of them relies on a different approximate algebra, leading to oscillatory dynamics in all cases. However, in contrast to the PXP model, their observation requires launching dynamics from weakly entangled initial states rather than from a product state. QMBSs reported here may be experimentally probed using Rydberg atom simulator in the regime of longer-range Rydberg blockades."}],"day":"22","publication_status":"published","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"publisher":"American Physical Society","doi":"10.1103/PhysRevLett.134.160401","department":[{"_id":"MaSe"}],"publication":"Physical Review Letters","issue":"16","date_published":"2025-04-22T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Quantum many-body scars beyond the PXP model in Rydberg simulators","acknowledgement":"The authors are grateful to Zlatko Papić, Dolev Bluvstein, Nishad Maskara, Marcello Dalmonte, Thomas Iadecola, and Johannes Feldmeier for insightful discussions.
