Out-of-equilibrium cesium atoms reveal fractional Fermi seas, exposing new critical quantum phase

In a new study published in Physical Review Letters, a team from the Nägerl group, together with theory collaborator Alvise Bastianello from the CNRS and the Université Paris-Dauphine, demonstrates that highly unusual quantum states known as "fractional Fermi seas" can be quantum engineered.
