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"}],"_id":"8726","date_published":"2020-08-26T00:00:00Z","arxiv":1,"article_processing_charge":"No","issue":"3","language":[{"iso":"eng"}],"doi":"10.3390/condmat5030053","ddc":["530"],"project":[{"call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425","grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships"}],"day":"26","author":[{"full_name":"Gotfryd, Dorota","first_name":"Dorota","last_name":"Gotfryd"},{"full_name":"Paerschke, Ekaterina","first_name":"Ekaterina","last_name":"Paerschke","id":"8275014E-6063-11E9-9B7F-6338E6697425","orcid":"0000-0003-0853-8182"},{"first_name":"Krzysztof","full_name":"Wohlfeld, Krzysztof","last_name":"Wohlfeld"},{"full_name":"Oleś, Andrzej M.","first_name":"Andrzej M.","last_name":"Oleś"}],"type":"journal_article","citation":{"ama":"Gotfryd D, Paerschke E, Wohlfeld K, Oleś AM.
