Our analysis suggests the existence of an underlying nonintegrableHamiltonian which supports an emergent SU(2)-spin dynamics within a small subspace of the many-bodyHilbert space. We show that such perfect dynamics necessitates the existence of atypical, nonergodicenergy eigenstates—quantum many-body scars. Furthermore, using these insights, we construct a toymodel that hosts exact quantum many-body scars, providing an intuitive explanation of their origin. Ourresults offer specific routes to enhancing coherent many-body revivals and provide a step towardestablishing the stability of quantum many-body scars in the thermodynamic limit."}],"date_updated":"2024-02-28T13:12:22Z","intvolume":"       122","main_file_link":[{"url":"https://arxiv.org/abs/1812.05561","open_access":"1"}],"publication_status":"published","oa":1,"scopus_import":"1","publisher":"American Physical Society","citation":{"apa":"Choi, S., Turner, C.
