Physicists Report a “Fractional Fermi Sea” in Ultracold Atoms
Key Takeaways
- Researchers repeatedly cycled ultracold cesium atoms between repulsive and attractive interactions.
- The team reports a highly excited state with hidden order called a fractional Fermi sea.
- The work offers a new setting for studying quantum many-body systems far from equilibrium.
