Paper Abstract

Optical traps provide tight confinement and very long storage times for atomic gases. Using a single focused beam from a CO2 laser, we confine a mixture of spin-up and spin-down fermionic 6Li atoms, achieving storage times of ten minutes, and evaporative cooling to quantum degeneracy in seconds. A bias magnetic field tunes the gas to a collisional (Feshbach) resonance, producing extremely strong spin-pairing. This system now tests current many-body predictions for high-temperature superconductors, universal interactions in neutron stars, and hydrodynamic flow of quark-gluon plasmas, a state of matter that existed microseconds after the Big Bang.
