The research activity of our group focuses on ultracold atoms and cavity quantum electrodynamics. The group is currently setting up a laboratory for optical experiments with Rubidium atoms, which will be developed to realize a multi-purpose quantum light-matter interface during the period of the PhD scholarship. The quantum field of an optical cavity will be strongly coupled to electric dipole transitions of Rubidium atoms. The atoms are cooled by lasers into the microKelvin range where the slow and trapped atoms can be loaded into the resonator volume. The cold atom cloud rtealizes a non-lienar optical medium where qunatum information processing of light and m,icrowave radiation is possible. The successful applicant will be given the opportunity to learn the current experimental techniques of quantum optics while becoming proficient in the fundamental processes of light-matter interaction.
