  text: Persistent revivals recently observed in Rydberg atom simulators have challenged
    our understanding of thermalization and attracted much interest to the concept
    of quantum many-body scars (QMBSs). 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.
