Tracing microscopic mechanisms of the OAM transfer, we derive rotational selection rules, which establish that HD emerges only from the spin–orbit coupling of light, even for beams without the far-field OAM. Our findings refine the conditions for observing HD, provide a tool to re-examine the outcome of prior experiments, and guide future designs for chiral sensing with structured light.","lang":"eng"}],"doi":"10.1103/fkf1-1jml","external_id":{"arxiv":["2505.16393"]},"project":[{"_id":"7c040762-9f16-11ee-852c-dd79eeee4ab3","name":"Coherent Optical Metrology Beyond Electric-Dipole-Allowed Transitions","grant_number":"F100403"}],"volume":136,"acknowledgement":"This research was funded in whole or in part by the Austrian Science Fund (FWF) [10.55776/F1004].","file_date_updated":"2026-02-10T11:25:46Z","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"publisher":"American Physical Society","publication":"Physical Review Letters","type":"journal_article","day":"05","arxiv":1,"date_updated":"2026-02-10T11:30:37Z","date_created":"2026-02-06T10:53:17Z","status":"public"}
