Enantioselective orientation of chiral molecules induced by terahertz pulses with twisted polarization

Chirality and chiral molecules are key elements in modern chemical biochemical industries. Individual addressing the eventual separation of enantiomers have been still important elusive tasks molecular physics chemistry, a variety methods introduced over years to achieve these goals. Here, we theoretically demonstrate that pair cross-polarized THz pulses interacting with through their permanent dipole moments induces an enantioselective orientation. This orientation persists for long time, exceeding duration by several orders magnitude, its dependency on temperature pulses' parameters is investigated. persistent may enhance deflection inhomogeneous electromagnetic fields, potentially leading viable techniques.Received 16 December 2020Accepted 24 February 2021DOI:https://doi.org/10.1103/PhysRevResearch.3.013249Published American Physical Society under terms Creative Commons Attribution 4.0 International license.
