The states with spin ±1 in the confinement direction are energetically favored by up to 55 μeV compared to the spin 0 triplet state because of the strong spin–orbit coupling. The reported effect should be observable in a broad class of strongly confined hole quantum-dot systems and might need to be considered when operating hole spin qubits."}],"department":[{"_id":"GeKa"}],"day":"01","type":"journal_article","file":[{"relation":"main_file","file_name":"2020_NanoLetters_Katsaros.pdf","creator":"dernst","access_level":"open_access","content_type":"application/pdf","date_updated":"2020-08-06T09:35:37Z","date_created":"2020-08-06T09:35:37Z","file_size":3308906,"file_id":"8204","success":1}],"date_updated":"2024-02-21T12:44:01Z","pmid":1,"tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"article_processing_charge":"Yes (via OA deal)","month":"06","status":"public","related_material":{"record":[{"status":"public","relation":"research_data","id":"7689"}]},"quality_controlled":"1","title":"Zero field splitting of heavy-hole states in quantum dots","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","date_created":"2020-08-06T09:25:04Z","oa_version":"Published Version","oa":1,"scopus_import":"1","publisher":"American Chemical Society","article_type":"original","citation":{"ama":"Katsaros G, Kukucka J, Vukušić L, et al.
