Address of unit: 
1121 Budapest, Konkoly-Thege Miklós út 29-33.
Description: 

The aim of the candidate will be to develop and characterize a high-efficiency interface between atoms and photons, enabling strong coupling and coherent conversion between microwave and optical domains.

The system will utilize cold atoms loaded from a movable magnetic quadrupole trap into a single-mode, high-finesse optical resonator.
The project will also incorporate data acquisition via single-photon counting techniques, enabling precise characterization of states and conversion efficiency. Statistical physics methods will be applied to analyze photon count distributions amd system dynamics under varying coupling regimes.
