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.","lang":"eng"}],"ec_funded":1,"pmid":1,"oa":1,"department":[{"_id":"GeKa"}],"title":"Zero field splitting of heavy-hole states in quantum dots","article_processing_charge":"Yes (via OA deal)","language":[{"iso":"eng"}],"date_created":"2020-08-06T09:25:04Z","publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"file_date_updated":"2020-08-06T09:35:37Z","intvolume":"        20","acknowledged_ssus":[{"_id":"NanoFab"},{"_id":"M-Shop"}],"project":[{"call_identifier":"FWF","name":"Towards scalable hut wire quantum devices","grant_number":"P32235","_id":"237B3DA4-32DE-11EA-91FC-C7463DDC885E"},{"name":"TOPOLOGICALLY PROTECTED AND SCALABLE QUANTUM BITS","grant_number":"862046","_id":"237E5020-32DE-11EA-91FC-C7463DDC885E","call_identifier":"H2020"}],"day":"01","issue":"7","page":"5201-5206","citation":{"mla":"Katsaros, Georgios, et al. “Zero Field Splitting of Heavy-Hole States in Quantum Dots.” <i>Nano Letters</i>, vol. 20, no. 7, American Chemical Society, 2020, pp. 5201–06, doi:<a href=\"https://doi.org/10.1021/acs.nanolett.0c01466\">10.1021/acs.nanolett.0c01466</a>.","ista":"Katsaros G, Kukucka J, Vukušić L, Watzinger H, Gao F, Wang T, Zhang J-J, Held K. 2020.
