Physicists Set Sail on a Strange Quantum State Called a Fractional Fermi Sea
Insider Brief Researchers reported that a driven one-dimensional gas of ultracold cesium atoms can be engineered into a highly ordered non-equilibrium quantum state known as a fractional Fermi sea. The study shows that cyclically changing interactions between strongly repulsive and strongly attractive regimes can reorganize atoms into a highly excited state rather than simply heating … Read more
