Probing Interactions between Ultracold Fermions
G. K. Campbell, M. M. Boyd, J. W. Thomsen +12
At ultracold temperatures, the Pauli exclusion principle suppresses collisions between identical fermions. This has motivated the development of atomic clocks using fermionic isoto…
The absolute frequency of the 87Sr optical clock transition
Gretchen K. Campbell, Andrew D. Ludlow, Sebastian Blatt +10
The absolute frequency of the 1S0-3P0 clock transition of 87Sr has been measured to be 429 228 004 229 873.65 (37) Hz using lattice-confined atoms, where the fractional uncertainty…
Sr lattice clock at 1x10^{-16} fractional uncertainty by remote optical evaluation with a Ca clock
A. D. Ludlow, T. Zelevinsky, G. K. Campbell +16
Optical atomic clocks promise timekeeping at the highest precision and accuracy, owing to their high operating frequencies. Rigorous evaluations of these clocks require direct comp…
Phase diagram for a Bose-Einstein condensate moving in an optical lattice
Jongchul Mun, Patrick Medley, Gretchen K. Campbell +3
The stability of superfluid currents in a system of ultracold bosons was studied using a moving optical lattice. Superfluid currents in a very weak lattice become unstable when the…
Atom trapping with a thin magnetic film
Micah Boyd, Erik W. Streed, Patrick Medley +4
We have created a Rb Bose-Einstein condensate in a magnetic trapping potential produced by a hard disk platter written with a periodic pattern. Cold atoms were loaded from a…
Imaging the Mott Insulator Shells using Atomic Clock Shifts
Gretchen K. Campbell, Jongchul Mun, Micah Boyd +5
Microwave spectroscopy was used to probe the superfluid-Mott Insulator transition of a Bose-Einstein condensate in a 3D optical lattice. Using density dependent transition frequenc…
