Magneto-Optical Trap for Polar Molecules
Benjamin K. Stuhl, Brian C. Sawyer, Dajun Wang +1
We propose a method for laser cooling and trapping a substantial class of polar molecules, and in particular titanium (II) oxide (TiO). This method uses pulsed electric fields to n…
Low-energy molecular collisions in a permanent magnetic trap
Brian C. Sawyer, Benjamin K. Stuhl, Dajun Wang +2
Cold, neutral hydroxyl radicals are Stark decelerated and confined within a magnetic trap consisting of two permanent ring magnets. The OH molecules are trapped in the ro-vibration…
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…
New Limits on Coupling of Fundamental Constants to Gravity Using Sr Optical Lattice Clocks
S. Blatt, A. D. Ludlow, G. K. Campbell +13
The - clock transition frequency in neutral Sr has been measured relative to the Cs standard by three independent laboratories…
