Our approach is based on combining a circularly polarized femtosecond fundamental field of frequency ω with its counterrotating second harmonic 2ω. We demonstrate the ability of bicircular high-harmonic spectroscopy to characterize the orbital angular momentum symmetry of atomic orbitals. We further show that breaking the threefold rotational symmetry of the generating medium-at the level of either the ensemble or that of a single molecule-results in the emission of the otherwise parity-forbidden frequencies 3qω  (q∈N), which provide a background-free probe of dynamical molecular symmetries.","lang":"eng"}],"status":"public","intvolume":"       116","date_updated":"2023-08-22T08:44:10Z","quality_controlled":"1","day":"25","title":"Bicircular high-harmonic spectroscopy reveals dynamical symmetries of atoms and molecules","month":"03","issue":"12","_id":"14011","doi":"10.1103/physrevlett.116.123001","publication_identifier":{"eissn":["1079-7114"],"issn":["0031-9007"]},"citation":{"short":"D.R.
