He is specialized in the study of ultra-cold atoms trapped and manipulated by magnetic fields, radio frequencies and lasers, in order to study the superfluid properties of
Bose-Einstein condensates.

He is particularly interested in the use of these well-controlled systems to study phenomena in non-linear physics: shock wave formation, solitons, and systems very far from their equilibrium state.

Romain Dubessy will be starting a new experimental activity at the PIIM laboratory at the interface of plasma physics and ultra-cold atoms by building a platform for studying ultra-cold calcium neutral plasmas, cooled and controlled by lasers)
