--- res: bibo_abstract: - Using inelastic cotunneling spectroscopy we observe a zero field splitting within the spin triplet manifold of Ge hut wire quantum dots. 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.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Georgios foaf_name: Katsaros, Georgios foaf_surname: Katsaros foaf_workInfoHomepage: http://www.librecat.org/personId=38DB5788-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-8342-202X - foaf_Person: foaf_givenName: Josip foaf_name: Kukucka, Josip foaf_surname: Kukucka foaf_workInfoHomepage: http://www.librecat.org/personId=3F5D8856-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Lada foaf_name: Vukušić, Lada foaf_surname: Vukušić foaf_workInfoHomepage: http://www.librecat.org/personId=31E9F056-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0003-2424-8636 - foaf_Person: foaf_givenName: Hannes foaf_name: Watzinger, Hannes foaf_surname: Watzinger foaf_workInfoHomepage: http://www.librecat.org/personId=35DF8E50-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Fei foaf_name: Gao, Fei foaf_surname: Gao - foaf_Person: foaf_givenName: Ting foaf_name: Wang, Ting foaf_surname: Wang orcid: 0000-0002-4619-9575 - foaf_Person: foaf_givenName: Jian-Jun foaf_name: Zhang, Jian-Jun foaf_surname: Zhang - foaf_Person: foaf_givenName: Karsten foaf_name: Held, Karsten foaf_surname: Held bibo_doi: 10.1021/acs.nanolett.0c01466 bibo_issue: '7' bibo_volume: 20 dct_date: 2020^xs_gYear dct_identifier: - UT:000548893200066 dct_isPartOf: - http://id.crossref.org/issn/1530-6984 - http://id.crossref.org/issn/1530-6992 dct_language: eng dct_publisher: American Chemical Society@ dct_title: Zero field splitting of heavy-hole states in quantum dots@ fabio_hasPubmedId: '32479090' ...
