Suppression of Three-Body Loss Near a p-Wave Resonance Due to Quasi-1D Confinement
Andrew S. Marcum, Francisco R. Fonta, Arif Mawardi Ismail +1
We investigate the three-body recombination rate of a Fermi gas of Li atoms confined in quasi-1D near a -wave Feshbach resonance. We confirm that the quasi-1D loss rate cons…
A self-injected, diode-pumped, solid-state ring laser for laser cooling of Li atoms
Yudai Miake, Takashi Mukaiyama, Kenneth M. O'Hara +1
We have constructed a solid-state light source for experiments with laser cooled lithium atoms based on a Nd:YVO ring laser with second-harmonic generation. Unidirectional lasi…
S-Wave Collisional Frequency Shift of a Fermion Clock
Eric L. Hazlett, Yi Zhang, Ronald W. Stites +2
We report an s-wave collisional frequency shift of an atomic clock based on fermions. In contrast to bosons, the fermion clock shift is insensitive to the population difference of…
Three-body recombination in a three-state Fermi gas with widely tunable interactions
J. H. Huckans, J. R. Williams, E. L. Hazlett +2
We investigate the stability of a three spin state mixture of ultracold fermionic Li atoms over a range of magnetic fields encompassing three Feshbach resonances. For most fiel…
Stable, Strongly Attractive, Two-State Mixture of Lithium Fermions in an Optical Trap
K. M. O'Hara, M. E. Gehm, S. R. Granade +2
We use an all-optical trap to confine a strongly attractive two-state mixture of lithium fermions. By measuring the rate of evaporation from the trap, we determine the effective el…
Ultrastable CO2 Laser Trapping of Lithium Fermions
K. M. O'Hara, S. R. Granade, M. E. Gehm +4
We demonstrate an ultrastable CO2 laser trap that provides tight confinement of neutral atoms with negligible optical scattering and minimal laser-noise- induced heating. Using thi…
