Ultracold Atoms as Coherent Systems

We investigate the transmission probability of an ultracold V-type three-level atom passing through a micromaser cavity, in the presence of atomic coherence which is established by a coherent driving field. We show that the transmissibility of this micromaser system with the atomic coherence is better than that of the ordinary micromaser system without atomic coherence. When the driving field is strong enough, for any cavity length the ultracold atom can pass through the micromaser cavity freely.

The authors observe the restoration of coherence in a system where a discrete energy level is coupled to a broadband continuum. The phenomenon is demonstrated in the well-controlled and tunable environment of a thermal gas of ultracold atoms.
