  bibo_abstract:
  - The thermodynamic description of many-particle systems rests on the assumption
    of ergodicity, the ability of a system to explore all allowed configurations in
    the phase space. Recent studies on many-body localization have revealed the existence
    of systems that strongly violate ergodicity in the presence of quenched disorder.
    Here, we demonstrate that ergodicity can be weakly broken by a different mechanism,
    arising from the presence of special eigenstates in the many-body spectrum that
    are reminiscent of quantum scars in chaotic non-interacting systems. In the single-particle
    case, quantum scars correspond to wavefunctions that concentrate in the vicinity
    of unstable periodic classical trajectories. We show that many-body scars appear
    in the Fibonacci chain, a model with a constrained local Hilbert space that has
    recently been experimentally realized in a Rydberg-atom quantum simulator. The
    quantum scarred eigenstates are embedded throughout the otherwise thermalizing
    many-body spectrum but lead to direct experimental signatures, as we show for
    periodic recurrences that reproduce those observed in the experiment. Our results
    suggest that scarred many-body bands give rise to a new universality class of
    quantum dynamics, opening up opportunities for the creation of novel states with
    long-lived coherence in systems that are now experimentally realizable.@eng
