Experiments on these materials confirm that spin-orbital entanglement has measurable consequences. Here, we capture the essential features of spin-orbital entanglement in complex quantum matter utilizing 1D spin-orbital model which accommodates SU(2)⊗SU(2) symmetric Kugel-Khomskii superexchange as well as the Ising on-site spin-orbit coupling. Building on the results obtained for full and effective models in the regime of strong spin-orbit coupling, we address the question whether the entanglement found on superexchange bonds always increases when the Ising spin-orbit coupling is added. We show that (i) quantum entanglement is amplified by strong spin-orbit coupling and, surprisingly, (ii) almost classical disentangled states are possible. We complete the latter case by analyzing how the entanglement existing for intermediate values of spin-orbit coupling can disappear for higher values of this coupling."],"identifier":["https://research-explorer.ista.ac.at/record/8726","https://research-explorer.ista.ac.at/download/8726/8727"],"title":["Evolution of spin-orbital entanglement with increasing ising spin-orbit coupling"],"language":["eng"],"rights":["https://creativecommons.org/licenses/by/4.0/","info:eu-repo/semantics/openAccess"],"creator":["Gotfryd, Dorota","Paerschke, Ekaterina","Wohlfeld, Krzysztof","Oleś, Andrzej M."],"subject":["ddc:530"]},"day":"26","has_accepted_license":"1","oa":1,"quality_controlled":"1","file_date_updated":"2020-11-06T07:24:40Z","department":[{"_id":"MiLe","tree":[{"_id":"ResearchGroups"},{"_id":"IST"}]}],"ddc":[],"creator":{"login":"dernst","id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},"date_updated":"2021-01-12T08:20:46Z","status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"type":"journal_article","article_type":"original","_id":"8726","ec_funded":1,"issue":"3","volume":5,"language":[{}],"file":[{"date_created":"2020-11-06T07:24:40Z","file_name":"2020_CondensedMatter_Gotfryd.pdf","date_updated":"2020-11-06T07:24:40Z","file_size":768336,"creator":"dernst","checksum":"a57a698ff99a11b6665bafd1bac7afbc","file_id":"8727","success":1,"content_type":"application/pdf","access_level":"open_access","relation":"main_file"}],"publication_status":"published","publication_identifier":{"issn":[]},"intvolume":" 5","month":"08","scopus_import":"1","oa_version":"Published Version","abstract":[{"lang":"eng"}]}]
