Frédéric Chevy is professor at the École Normale Supérieure in Paris. He studies the dynamics of quantum as well as classical fluids and his latest research involves the study of strongly interacting Bose gases and of mixtures of bosonic and fermionic superfluids.

Atomic and Molecular Physics

Viewpoint: Swimming in the Fermi sea

The fermionic analog of a solid-state polaron (an electron surrounded by a cloud of phonons) has been created by dropping a spin-down atom into a Fermi sea of spin-up ultracold atoms. Read More »


Viewpoint: Solitons with a Twist

Two independent groups have shown that certain defects in superfluids can be identified as solitonic vortices. Read More »
