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.","lang":"eng"}],"article_type":"original","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1812.05561"}],"date_created":"2019-06-23T21:59:13Z","year":"2019","issue":"22","author":[{"first_name":"Soonwon","last_name":"Choi","full_name":"Choi, Soonwon"},{"last_name":"Turner","full_name":"Turner, Christopher J.","first_name":"Christopher J."},{"full_name":"Pichler, Hannes","last_name":"Pichler","first_name":"Hannes"},{"last_name":"Ho","full_name":"Ho, Wen Wei","first_name":"Wen Wei"},{"id":"36EBAD38-F248-11E8-B48F-1D18A9856A87","first_name":"Alexios","last_name":"Michailidis","full_name":"Michailidis, Alexios","orcid":"0000-0002-8443-1064"},{"first_name":"Zlatko","last_name":"Papić","full_name":"Papić, Zlatko"},{"orcid":"0000-0002-2399-5827","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","first_name":"Maksym","last_name":"Serbyn","full_name":"Serbyn, Maksym"},{"first_name":"Mikhail D.","last_name":"Lukin","full_name":"Lukin, Mikhail D."},{"last_name":"Abanin","full_name":"Abanin, Dmitry A.","first_name":"Dmitry A."}],"type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"}
