Observation of a Strongly Interacting Degenerate Fermi Gas of Atoms
Observation of a Strongly Interacting Degenerate Fermi Gas of Atoms
We report on the observation of a highly degenerate, strongly interacting Fermi gas of atoms. Fermionic lithium-6 atoms in an optical trap are evaporatively cooled to degeneracy using a magnetic field to induce strong, resonant interactions. Upon abruptly releasing the cloud from the trap, the gas is observed to expand …
