Heterodyne spectroscopy of single atom motional states inside a high-finesse cavity — •Natalie Thau, Wolfgang Alt, Tobias Kampschulte, Sebastian Manz, René Reimann, Seokchan Yoon, and Dieter Meschede — Institut für Angewandte Physik der Universität Bonn, Wegelerstr. 8, 53115 Bonn

Tight control and knowledge of the motional states of single atoms are a prerequisite for many experiments connected to the field of quantum information. In our system insight to the motional states of single atoms coupled to a high finesse optical resonator is gained by the means of optical heterodyne detection. Measuring the beat signal between a fixed-frequency local oscillator beam and the light interacting with the coupled atoms, we are able to map the atomic motional state to the frequency domain in a non-destructive way. Analysing the spectra we discuss different experimental imperfections and estimate the intra-cavity atomic temperature within the frame of a simple model.
