I'm an experimentalist physicist. The story line of my research is the manipulation of atoms by means of their interaction with lasers, with a preference for coherent process. Since few years, my main research is focused on the study of laser cooled large ion clouds, trapped in radio-frequency trap of different geometry. The TADOTI experiment, built for this study, is financially supported by the french national research agency (ANR). CNES (the french center for spacial research) is also involved due to the common points of TADOTI with micro-wave standard prototypes developed by JPL for the NASA.
Here is the picture of an ion cloud emitting laser induced fluorescence. It is made of several tens of thousands of calcium ions, laser cooled and trapped in a linear Paul trap. The elliptic shape is the signature of a correlated phase (liquid or crystal) whereas the layers which can be seen on the cloud demonstrate a local self-organization in a Coulomb crystal where the radio-frequency electric field is minimal, around the symmetry axis of the trap.
A three-photon coherent population trapping, discovered in calcium like ions, allow us to propose a STIRAP-like scheme between the two metastable states of these ions. These laser interaction protocols can be used to build quantum memories. The advantage of a three photon coupling scheme is the exact cancellation of the first order Doppler effect. It makes the process suitable for an ion cloud, an example of a mesoscopic system.
After you enjoy tremendous plenary sessions, and so promising quantum optique and AMO conferences, come and meet me at the Women in Physics desk at any coffee-break! The French Optical Society has now its Women in Physics committee and we are waiting for this big meeting to start a network of people who wants to make things move! Hope to meet there.
