Coherent rotational state control of chiral molecules — •Sandra Eibenberger-Arias — Fritz-Haber-Institut der Max-Planck-Gesellschaft, Berlin, Germany

Chiral molecules are ubiquitous in nature and they are of great importance in many biological and chemical processes. They are also at the center of some interesting fundamental physics questions, for example whether there is parity violation in chiral molecules, which has been long predicted but never experimentally observed.

I will present important recent experimental developments targeted at the understanding and the control of cold, chiral molecules in the gas phase. I will discuss enantiomer-specific state transfer (ESST) [1], an all-coherent method to populate a chosen rotational state preferentially with one enantiomer, providing a way of quantum-controlled chiral separation. In recent experiments [2,3], we realize increased control of chiral molecules. We employ a quantitative comparison between experiment and theory for the transfer efficiency of ESST. Straightforward extensions to our scheme will allow to create a molecular beam with an enantiomer-pure rotational level, holding great prospects for future spectroscopic and scattering studies.
