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"}],"citation":{"mla":"Baykusheva, Denitsa Rangelova, et al. “Bicircular High-Harmonic Spectroscopy Reveals Dynamical Symmetries of Atoms and Molecules.” Physical Review Letters, vol. 116, no. 12, 123001, American Physical Society, 2016, doi:10.1103/physrevlett.116.123001.","ieee":"D.
