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.","lang":"eng"}],"publication_identifier":{"issn":["2410-3896"]},"month":"08","doi":"10.3390/condmat5030053","ddc":["530"],"_id":"8726","oa_version":"Published Version","status":"public","has_accepted_license":"1","volume":5,"publication":"Condensed Matter","file":[{"file_size":768336,"access_level":"open_access","relation":"main_file","date_created":"2020-11-06T07:24:40Z","checksum":"a57a698ff99a11b6665bafd1bac7afbc","creator":"dernst","success":1,"file_id":"8727","date_updated":"2020-11-06T07:24:40Z","content_type":"application/pdf","file_name":"2020_CondensedMatter_Gotfryd.pdf"}],"citation":{"ieee":"D.
