RESEARCH TOPICS: QUANTUM FLUIDS

There are two periods in my research activities on quantum fluids:
3-body recombination
"Schematic view of an inelastic collision of 3 atoms giving rise to the formation of a molecule. Three-body recombination processes are essential for explaining the lifetime of cold atomic gases. They have been a key feature leading to the first experimental evidence of the Efimov effect."

PICTURES

You can see below a cut of the velocity field associated with a rotating Bose-Einstein condensate at finite temperature. In this picture, finite temperature effects result in the creation of satellite vortices surrouding the condensate.
