The nodes in both real and imaginary parts of the measured complex transmittance are analyzed using a dynamic version of the static Lifshitz-Kosevich formula. These results demonstrate that the node structure of the dynamic SdH oscillations provides an all-optical access to quantization- and interaction-induced renormalization effects, in addition to parameters one can obtain from the static SdH oscillations.","lang":"eng"}],"language":[{"iso":"eng"}],"quality_controlled":"1","type":"journal_article","issue":"2","DOAJ_listed":"1","scopus_import":"1","status":"public","date_updated":"2025-05-14T09:31:15Z","publication":"Physical Review Research","file_date_updated":"2024-05-22T06:39:35Z","title":"Optical Shubnikov-de Haas oscillations in two-dimensional electron systems","date_created":"2024-05-19T22:01:12Z","oa_version":"Published Version","publication_identifier":{"eissn":["2643-1564"]},"arxiv":1,"file":[{"file_size":1697856,"date_created":"2024-05-22T06:39:35Z","success":1,"content_type":"application/pdf","access_level":"open_access","file_id":"15412","relation":"main_file","date_updated":"2024-05-22T06:39:35Z","creator":"dernst","file_name":"2024_PhysicalReviewResearch_Savchenko.pdf","checksum":"78c8c3cf1bda766e3de0db45f143a367"}],"publication_status":"published","article_processing_charge":"Yes","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"publisher":"American Physical Society","author":[{"full_name":"Savchenko, M.

A smooth transition through the charge neutrality point between Dirac holes and electrons was observed. An additional peak coming from a second type of holes with an almost density-independent mass of around 0.04m0 was detected in the hole-doping range and attributed to an asymmetric spin splitting of the Dirac cone.
