In our previous work [C. J. Turner et al., Nat. Phys. 14, 745 (2018)], such dynamics was attributed to the existence of “quantum scarred” eigenstates in the many-body spectrum of the experimentally realized model. Here, we present a detailed study of the eigenstate properties of the same model. We find that the majority of the eigenstates exhibit anomalous thermalization: the observable expectation values converge to their Gibbs ensemble values, but parametrically slower compared to the predictions of the eigenstate thermalization hypothesis (ETH). Amidst the thermalizing spectrum, we identify nonergodic eigenstates that strongly violate the ETH, whose number grows polynomially with system size. Previously, the same eigenstates were identified via large overlaps with certain product states, and were used to explain the revivals observed in experiment. Here, we find that these eigenstates, in addition to highly atypical expectation values of local observables, also exhibit subthermal entanglement entropy that scales logarithmically with the system size. Moreover, we identify an additional class of quantum scarred eigenstates, and discuss their manifestations in the dynamics starting from initial product states. We use forward scattering approximation to describe the structure and physical properties of quantum scarred eigenstates. Finally, we discuss the stability of quantum scars to various perturbations. We observe that quantum scars remain robust when the introduced perturbation is compatible with the forward scattering approximation. In contrast, the perturbations which most efficiently destroy quantum scars also lead to the restoration of “canonical” thermalization.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"44","intvolume":" 98","status":"public","title":"Quantum scarred eigenstates in a Rydberg atom chain: Entanglement, breakdown of thermalization, and stability to perturbations","oa_version":"Preprint","month":"10","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1806.10933"}],"external_id":{"arxiv":["1806.10933"],"isi":["000447919100001"]},"oa":1,"isi":1,"quality_controlled":"1","doi":"10.1103/PhysRevB.98.155134","language":[{"iso":"eng"}],"acknowledged_ssus":[{"_id":"ScienComp"}],"article_number":"155134","publist_id":"8010","year":"2018","publisher":"American Physical Society","department":[{"_id":"MaSe"}],"publication_status":"published","author":[{"first_name":"C J","last_name":"Turner","full_name":"Turner, C J"},{"first_name":"Alexios","last_name":"Michailidis","id":"36EBAD38-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8443-1064","full_name":"Michailidis, Alexios"},{"full_name":"Abanin, D A","first_name":"D A","last_name":"Abanin"},{"first_name":"Maksym","last_name":"Serbyn","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2399-5827","full_name":"Serbyn, Maksym"},{"full_name":"Papić, Z","last_name":"Papić","first_name":"Z"}],"volume":98,"date_created":"2018-12-11T11:44:19Z","date_updated":"2023-10-10T13:28:49Z"},{"day":"19","article_processing_charge":"No","scopus_import":"1","date_published":"2018-03-19T00:00:00Z","publication":"Physical Review Letters","citation":{"chicago":"Choueiri, George H, Jose M Lopez Alonso, and Björn Hof. “Exceeding the Asymptotic Limit of Polymer Drag Reduction.” Physical Review Letters.

While drag reduction initially increases with polymer concentration, it eventually saturates to what is known as the maximum drag reduction (MDR) asymptote; this asymptote is generally attributed to the dynamics being reduced to a marginal yet persistent state of subdued turbulent motion. Contrary to this accepted view, we show that, for an appropriate choice of parameters, polymers can reduce the drag beyond the suggested asymptotic limit, eliminating turbulence and giving way to laminar flow. At higher polymer concentrations, however, the laminar state becomes unstable, resulting in a fluctuating flow with the characteristic drag of the MDR asymptote. Our findings indicate that the asymptotic state is hence dynamically disconnected from ordinary turbulence. © 2018 American Physical Society."}],"issue":"12","type":"journal_article","oa_version":"Preprint","status":"public","title":"Exceeding the asymptotic limit of polymer drag reduction","intvolume":" 120","_id":"328","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"03","acknowledged_ssus":[{"_id":"SSU"}],"language":[{"iso":"eng"}],"doi":"10.1103/PhysRevLett.120.124501","isi":1,"quality_controlled":"1","project":[{"_id":"25681D80-B435-11E9-9278-68D0E5697425","grant_number":"291734","call_identifier":"FP7","name":"International IST Postdoc Fellowship Programme"},{"_id":"25152F3A-B435-11E9-9278-68D0E5697425","grant_number":"306589","call_identifier":"FP7","name":"Decoding the complexity of turbulence at its origin"}],"external_id":{"isi":["000427804000005"]},"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1703.06271"}],"oa":1,"publist_id":"7537","ec_funded":1,"article_number":"124501","date_updated":"2023-10-10T13:27:44Z","date_created":"2018-12-11T11:45:51Z","volume":120,"author":[{"last_name":"Choueiri","first_name":"George H","id":"448BD5BC-F248-11E8-B48F-1D18A9856A87","full_name":"Choueiri, George H"},{"full_name":"Lopez Alonso, Jose M","id":"40770848-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0384-2022","first_name":"Jose M","last_name":"Lopez Alonso"},{"first_name":"Björn","last_name":"Hof","id":"3A374330-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2057-2754","full_name":"Hof, Björn"}],"publication_status":"published","department":[{"_id":"BjHo"}],"publisher":"American Physical Society","acknowledgement":"The authors thank Philipp Maier and the IST Austria workshop for their dedicated technical support.","year":"2018"},{"doi":"10.1103/PhysRevE.98.023105","language":[{"iso":"eng"}],"oa":1,"external_id":{"arxiv":["1808.02088"],"isi":["000441466800010"]},"main_file_link":[{"url":"https://arxiv.org/abs/1808.02088","open_access":"1"}],"quality_controlled":"1","isi":1,"month":"08","author":[{"first_name":"Balachandra","last_name":"Suri","id":"47A5E706-F248-11E8-B48F-1D18A9856A87","full_name":"Suri, Balachandra"},{"full_name":"Tithof, Jeffrey","first_name":"Jeffrey","last_name":"Tithof"},{"first_name":"Roman","last_name":"Grigoriev","full_name":"Grigoriev, Roman"},{"full_name":"Schatz, Michael","last_name":"Schatz","first_name":"Michael"}],"volume":98,"date_updated":"2023-10-10T13:29:10Z","date_created":"2018-12-11T11:44:49Z","year":"2018","department":[{"_id":"BjHo"}],"publisher":"American Physical Society","publication_status":"published","date_published":"2018-08-13T00:00:00Z","citation":{"ista":"Suri B, Tithof J, Grigoriev R, Schatz M. 2018.
