Strongly interacting quantum many-body systems are fundamentally compelling and ubiquitous in science. However, their complexity generally prevents exact solutions of their dynamics. Precisely engineered ultracold atomic gases are emerging as a power

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, currently limited by frequency shifts due to atomic interactions and room temperature

Advances in ultra-stable lasers now permit sub-Hz resolution of optical atomic transitions. At this level, weak interactions by any ordinary scale can in fact dominate the dynamics of the interrogated atoms, even for spin polarized fermions at ultral

By strongly confining atoms in a two-dimensional optical lattice, we have suppressed collisional frequency shifts in a 87Sr optical lattice clock.

Optical lattice clocks have the potential for extremely high frequency stability owing to the simultaneous interrogation of many atoms, but this precision may come at the cost of systematic inaccuracy due to atomic interactions. Density-dependent fre

We observe two-body loss of ${}^{3}\phantom{\rule{-0.16em}{0ex}}{P}_{0}$ ${}^{87}$Sr atoms trapped in a one-dimensional optical lattice. We measure loss rate coefficients for atomic samples between 1 and 6 $\ensuremath{\mu}$K that are prepared either

We report the observation of resolved atomic interaction sidebands (ISB) in the ${}^{87}$Sr optical clock transition when atoms at microkelvin temperatures are confined in a two-dimensional (2D) optical lattice. The ISB are a manifestation of the str
