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."}],"file":[{"access_level":"open_access","date_updated":"2020-11-06T07:24:40Z","checksum":"a57a698ff99a11b6665bafd1bac7afbc","file_size":768336,"creator":"dernst","file_name":"2020_CondensedMatter_Gotfryd.pdf","success":1,"date_created":"2020-11-06T07:24:40Z","file_id":"8727","relation":"main_file","content_type":"application/pdf"}],"article_number":"53","issue":"3","article_processing_charge":"No","arxiv":1,"publication_identifier":{"issn":["2410-3896"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2021-01-12T08:20:46Z","scopus_import":"1","external_id":{"arxiv":["2009.11773"]},"has_accepted_license":"1","year":"2020","oa_version":"Published Version","article_type":"original"}]
