Physicists Set Sail on a Strange Quantum State Called a Fractional Fermi Sea

Insider Brief PRESS RELEASE — In a new study published in Phys­ical Review Letters, a team of the Nägerl group jointly 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. By driving quantum particles, here ultracold Cesium atoms […]
