Characterization of an experimental setup to investigate cold molecule-Rydberg-atom interactions — •Martin Zeppenfeld — MPI für Quantenoptik

Strong interactions between molecules and Rydberg atom extend to distances larger than 1 µm, promising exciting applications in quantum science. This includes possibilities for cooling internal and external molecular degrees of freedom, nondestructive molecule detection and state readout, and performing quantum gates.

Towards these goals, I will present an experimental setup for the investigation of cold molecule-Rydberg-atom interactions. Cold molecules are produced via velocity filtering with an electrostatic quadrupole guide. Rydberg atoms are produced via two-photon excitation of ultracold atoms in a rubidium MOT. A key feature of the setup is a set of 24 electrodes, allowing the electric fields experienced by the Rydberg atoms to be precisely controlled. Combined with mm-waves at roughly 400−500 GHz to drive Rydberg transitions and state selective field ionization for detection, this allows precise control and read-out of the atomic Rydberg states.
