Coherent Control of Chiral Molecules
The project aims to generate an enantiomer-pure beam of chiral molecules from a racemic sample using advanced quantum state preparation and detection techniques.
Projectdetails
Introduction
The ambitious goal of this project is to create an enantiomer-pure beam of chiral molecules, starting from a racemic sample, using an experimental coherent state preparation scheme.
Experimental Setup
The basic elements of the proposed experiments are the following:
- A cold, gas-phase beam of chiral molecules is created via supersonic jet expansion.
- Two levels of a triad of rotational states that are connected via electric dipole allowed transitions are emptied using resonant UV depletion in combination with simultaneous microwave repumping.
- Driving a closed triad of rotational transitions using microwaves prepares a chosen internal quantum state of the chiral molecules enantiomer-specifically. This is called enantiomer-specific state transfer; a new method that I co-developed.
- After coherence preparation using collimation, state-selective matter-wave diffraction is accomplished using a resonant, absorptive optical grating.
Detection Method
The diffracted enantiomer-pure beam is detected state-selectively using 2D planar laser-induced fluorescence detection.
Applications
Eventually, this beam can be used for further spectroscopic or scattering studies or for depositing the enantiopure sample on a surface.
General Applicability
The scheme that is to be demonstrated in COCOCIMO will be applicable to any chiral molecule.
