Abstract:
In quantum optics, the dressed atom proved to be a useful concept for
Cohen-Tannoudji and Reynaud in the analysis of resonance fluorescence from
an atom back in 1977 [1]. More recently it has been found that by
adiabatically dressing atoms with radio-frequency and microwave radiation
we can produce a variety of different types of spatial trap for ultra-cold
atoms (see reviews in Refs. [2, 3]). In this talk we will see how shell
potentials can be tuned and the results and applications for dressing and
probing RF dressed potentials with microwave pulses.
