Main activities
We study the physics of single two-dimensional Bose gases of 87Rb atoms. Using spatial light modulators we can create arbitrary density profiles inside a box potential.
We exploit this versatility to explore many different aspects of quantum-many body physics: thermodynamics, the Kosterlitz-Thouless topological phase transition, superfluidity, sound propagation, light scattering in optically dense media, solitons and breathers … For details see our recent projects
New generation machine to explore Rydberg physics
In the framework of an ERC consolidator project, we are developing the next generation apparatus which will combine our expertise in 2D or 1D gases with the possibility to excite the atoms to Rydberg state and then enter the strongly correlated regime.
We recently achieved the realization of arrays of 3D BECs in all-optical traps with a less than 10s repetition rate !
