Precision spectroscopy and density-dependent frequency shifts in ultracold Sr

Abstract

By varying the density of an ultracold ${}^{88}$Sr sample from $10^9$ cm${}^{-3}$ to $>10^{12}$ cm${}^{-3}$, we make the first definitive measurement of the density-related frequency shift and linewidth broadening of the ${}^1{S}_0$ - ${}^3{P}_1$ optical clock transition in an alkaline earth system. In addition, we report the most accurate measurement to date of the ${}^{88}$Sr ${}^1{S}_0{-}^3{P}_1$ optical clock transition frequency. Including a detailed analysis of systematic errors, the frequency is ($434829121312334\pm 20_{stat}\pm 33_{sys}$) Hz.
