We present a unifying theoretical framework that describes recently observed many-body effects during the interrogation of an optical lattice clock operated with thousands of fermionic alkaline earth atoms. The framework is based on a many-body maste

Many-particle optical lattice clocks have the potential for unprecedented measurement precision and stability due to their low quantum projection noise. However, this potential has so far never been realized because clock stability has been limited b

We describe recent experimental progress with the JILA Sr optical frequency standard, which has a systematic uncertainty at the 10-(16) fractional frequency level. An upgraded laser system has recently been constructed in our lab which may allow the

We present measurements of Stark interference in the 6$^1S_0$ $\rightarrow$ 6$^3P_1$ transition in $^{199}$Hg, a process whereby a static electric field $E$ mixes magnetic dipole and electric quadrupole couplings into an electric dipole transition, l

We report the results of a new experimental search for a permanent electric dipole moment of $^{199}\mathrm{Hg}$ utilizing a stack of four vapor cells. We find $d(^{199}\mathrm{Hg})=(0.49\ifmmode\pm\else\textpm\fi{}{1.29}_{\mathrm{stat}}\ifmmode\pm\e

We report experimental evidence of Sisyphus cooling in atoms with a ${}^{1}{S}_{0}$ ground state. Since $J=0,$ any cooling mechanism which requires multiple sublevels can only occur in the isotopes which have nuclear spin $I\ensuremath{\ne}0.$ Ytterb
