Resonance fluorescence spectrum of a laser-cooled atom trapped in a non-harmonic potential — •Ralf Betzholz and Marc Bienert — Theoretische Physik, Universität des Saarlandes, D-66123 Saarbrücken, Germany

Single trapped atoms open the possibility of realizing well controlled quantum interfaces. When the atom, trapped in a non-harmonic potential, is cooled by a laser the spectral sidebands of the emitted light allow to monitor the dynamics of the motional degrees of freedom and the readout of the thermal distribution. We evaluate the laser cooling and the spectrum of resonance fluorescence for two examplary trapping potentials: an infinite square well potential and the Morse potential.
