Fractional Fermi seas: a new exotic phase of quantum matter
Physicists have discovered a new critical quantum phase called the fractional Fermi sea, created by driving ultracold cesium atoms far out of equilibrium through cyclic changes in their interactions. This highly ordered non-equilibrium state defies established theories and opens new pathways for quantum simulation.
