About

Ultracold neutral atoms are a powerful toolbox for studying a range of physical phenomenon. We have three major focus areas. The first looks at disordered lattice systems as an analog to condensed matter materials. The second project is an experiment that uses an interacting ytterbium/rubidium (boson-boson) mixture for studying dissipation (joint with Trey Porto). The third project is a hybrid project that combines ultracold atomic physics with superconducting CM devices. This project is a joint venture called Atoms-on-SQUIDs.

Our new vacuum chamber for studying disordered optical lattices is up and running, with recently dipole-trapped atoms moved into the science chamber. We are busily aligning lattice beams and anxious to see how this new design performs!

Peter Kordell, a UMD undergrad, was awarded the IPST Monroe Martin Prize for Undergraduate Research in Physics. Kordel, now a graduate student at University of Michigan, Ann Arbor, worked with Luis Orozco on the Atoms on SQUIDs experiment. His research paper was titled "Three Layer Optical Fiber...

In this paper, the team squeezes combinations of higher modes of the light into a nanofiber with unprecedented efficiency and purity. Ninety-seven percent passes through the tapered nanofiber—this is compared to previous work of around 20 percent. In contrast to a high purity fundamental mode,...

Modern precision measurements are spectacular feats of engineering. An excellent example is determining the passage of time. Before John Harrison’s marine chronometer in the mid 18th century, ship clocks lost so much time that the sailors themselves often became lost as well. Today’s global...
