The light-matter interaction Hamiltonian we derive is expressed through couplings between spherical gradients of the electric field and the (transition) electric multipole moments of a particle of any nontrivial rotation point group. Our model can therefore accommodate an arbitrary complexity of the molecular and electric field structure, and it can be straightforwardly extended to atoms or nanostructures. Applying this framework to rovibrational spectroscopy of molecules, we uncover the general mechanism of angular momentum exchange between the spin and orbital angular momenta of light, molecular rotation, and its center-of-mass motion. We show that the nonzero vorticity of Laguerre-Gaussian beams can strongly enhance certain rovibrational transitions that are considered forbidden in the case of nonhelical light. We discuss the experimental requirements for the observation of these forbidden transitions in state-of-the-art spatially resolved spectroscopy measurements.","lang":"eng"}],"publication_status":"published","project":[{"grant_number":"G341","name":"Coherent Optical Metrology Beyond Electric-Dipole-Allowed Transitions","_id":"7c040762-9f16-11ee-852c-dd79eeee4ab3"},{"call_identifier":"H2020","name":"IST-BRIDGE: International postdoctoral program","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","grant_number":"101034413"},{"name":"Angulon: physics and applications of a new quasiparticle","_id":"2688CF98-B435-11E9-9278-68D0E5697425","grant_number":"801770","call_identifier":"H2020"}],"intvolume":"         6","title":"Theory of angular momentum transfer from light to molecules","file":[{"content_type":"application/pdf","success":1,"creator":"dernst","checksum":"8f744d94956a1683b473b1cf9b411a37","date_created":"2024-09-23T09:46:20Z","file_name":"2024_PhysicalReviewResearch_Maslov.pdf","access_level":"open_access","file_size":1563824,"date_updated":"2024-09-23T09:46:20Z","relation":"main_file","file_id":"18125"}],"volume":6,"ddc":["530"],"_id":"18087","department":[{"_id":"GradSch"},{"_id":"MiLe"}],"oa":1,"year":"2024","publication":"Physical Review Research","publication_identifier":{"issn":["2643-1564"]},"doi":"10.1103/physrevresearch.6.033277","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"quality_controlled":"1","scopus_import":"1","month":"09"}
