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, for which the atoms need to be trapped in the cavity volume. We will realize two kinds of atomic medium: (i) cold atom gas in a magneto-optical trap and (ii) degenerate quantum gas of ultracold atoms, the so-called Bose-Einstein condensate. 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.
