|Title:||Blackbody effects in the Yb optical lattice clock|
|Published:||May 24, 2012|
|Abstract:||We report a high accuracy measurement of the differential static polarizability for the clock transition in a Yb lattice clock, a key parameter for determining the blackbody BBR) shift of this transition. We further report efforts to determine the 6s5d3D1-6s6p3P0 reduced dipole matrix element, a critical ingredient in the non-static correction to the BBR shift. In all, we have reduced the largest uncertainty in the Yb lattice clock (that stemming from the BBR shift) by an order of magnitude.|
