Measurement of Linear Stark Interference in 199Hg
T. H. Loftus, M. D. Swallows, W. C. Griffith +3
We present measurements of Stark interference in the 6 6 transition in Hg, a process whereby a static electric field mixes magnetic dipole a…
Precision spectroscopy and density-dependent frequency shifts in ultracold Sr
Tetsuya Ido, Thomas H. Loftus, Martin M. Boyd +3
By varying the density of an ultracold Sr sample from cm to cm, we make the first definitive measurement of the density-related frequency sh…
Narrow Line Cooling and Momentum-Space Crystals
Thomas H. Loftus, Tetsuya Ido, Martin M. Boyd +2
Narrow line laser cooling is advancing the frontier for experiments ranging from studies of fundamental atomic physics to high precision optical frequency standards. In this paper,…
Narrow Line Cooling: Finite Photon Recoil Dynamics
Thomas H. Loftus, Tetsuya Ido, Andrew D. Ludlow +2
We present an extensive study of the unique thermal and mechanical dynamics for narrow-line cooling on the 1S0 - 3P1 88Sr transition. For negative detuning, trap dynamics reveal a…
Resonant control of elastic collisions in an optically trapped Fermi gas of atoms
T. Loftus, C. A. Regal, C. Ticknor +2
We have loaded an ultracold gas of fermionic atoms into a far off resonance optical dipole trap and precisely controlled the spin composition of the trapped gas. We have measured a…
