The thermodynamic properties of unitary Fermi gases are called universal, since they do not depend on the strength or physical origin of their interactions. For the same reason, one might expect dynamics to be universal. We report on the growth of interactions and the loss of magnetization in a gas initialized with full transverse magnetization. Such a gas has no interaction energy, since each...

The ns → (n+1)s transition in alkali atoms is of interest due to its sensitivity to relativistic effects, and it has been the basis for the most stringent atomic parity non-conservation measurement by the Boulder group. We have carried out 5s→6s two-photon spectroscopy on rubidium kept in a vapor cell, with the aim of determining 6s hyperfine splittings and 5s→6s isotope shifts between...

Rydberg atoms --- large atoms with a highly excited, loosely bound electron --- may enable hybrid quantum systems, combining the long coherence times of atomic systems with the strong interactions of solid-state devices. However, this will require atoms to be located near a heterogeneous surface with exposed metal electrodes and dielectric insulators, which are sources of uncontrollable and...

The Francium Trapping Facility at TRIUMF has successfully commissioned a capture chamber and is in the process of completing a science chamber for weak interaction studies. We present recent isotope shift measurements of the 7S1/2 to 7P1/2 (D1) transition taken in the capture chamber by radiofrequency sideband spectroscopy. While isotope shifts in heavy elements are dominated by the field...
