At ultracold temperatures, the Pauli exclusion principle suppresses collisions between identical fermions. This has been a strong motivation for the development of optical atomic clocks using fermionic isotopes. At JILA we’ve developed an optical atomic clock with high accuracy and stability based on lattice confined 87 Strontium atoms. The uncertainty of the clock has now been evaluated at the 1E-16 level, surpassing the best current evaluations of Cs primary standards. During this evaluation, a nonzero density shift was measured for our lattice-confined fermionic atoms. Using our high spectroscopic resolution we’ve completed a study of these density shifts, and have explored quantum coherence in a one-dimensional optical lattice. The precision and control demonstrated by these experiments shows the promise of Strontium for both precision metrology and potentially quantum information science.

In 2006 I received my Ph.D from MIT, where I worked for Dave Pritchard and Wolfgang Ketterle on Rubidium condensates in optical lattices. My undergraduate work was done at Wellesley College. From 2007-2009 I was an NRC post-doc at JILA, where I worked in the group of Jun Ye. This September I joined the laser cooling and trapping group at NIST, and became a JQI fellow.
