Title of Research Topic : Random laser with cold atoms
Project Description :
We are currently investigating the possibility of realizing a random laser with cold atoms. We have already studied in detail a number of gain mechanisms and also
built a standard laser (with an external cavity) using cold atoms as the gain medium [1]. We have recently proven that a random laser with cold atoms is possible and also in reach of current experiments [2].
Further details can be found in our recent publication on this topic.
We are looking for an experienced researcher having a strong background in experimental work with laser cooling of atoms. The PhD position is to start in fall 2009.
Application will be open until the position is filled.

Title of Research Topic : Condensation of Photons with cold atoms
Project Description :
Propagation of wave in non linear media can be described by equations similar to the ones used to describe collision between particles. For
bosonic particles one spectacular consequence of such collisions is the possibility of the particles to occupy one single quantum state with a
macroscopic population (Bose-Einstein condensation). A similar process has been envisioned with photons [1] and the present status of
this field of research is that the adequate non linear medium still needs to be found to observe this condensation. We propose to use atomic
samples (possibly laser cooled) as a non linear medium [2]. In collaboration with A. Picozzi, we have implemented a first numerical simulation
of this process and now need to study the parameters available with hot or cold atoms, taken into account fundamental constrains such as
Kramers-Kronig relations.
We also offer experimental PhD work on Anderson localization of light in cold atoms and its connection to Dicke super- and subradiance [3].
PhD candidates should have a good knowledge of optics, atomic physics and quantum mechanics. An expertise in cold atom manipulation
would also be very useful, but is not required to start this research.
