Zitterbewegung, a force-free trembling motion first predicted for relativistic fermions like electrons, was an unexpected consequence of the Dirac equation’s unification of quantum mechanics and special relativity. Though the oscillatory motion’s large frequency and small amplitude have precluded its measurement with electrons, zitterbewegung is …

Citation: For innovative and pioneering work in quantum phenomena at the intersection of atomic and condensed matter physics, using quantum simulation with ultracold atoms, including the use of optical interactions to create artificial electromagnetic fields and spin-orbit coupling.
We are delighted and proud that Karina has been selected as a finalist for the 2013 DAMOP thesis prize! Karina (remotely) presented her thesis research in the special Prize Session at DAMOP this year.
Electronic properties such as current flow are generally independent of the electron’s spin angular momentum, an internal degree of freedom possessed by quantum particles. The spin Hall effect, first proposed 40 years ago, is an unusual class of phenomena in …
Matthew Beeler —the first observer of a spin-Hall effect in a Bose-Einstein condensate— just moved on to a staff scientist position at the the Johns Hopkins University Applied Physics Laboratory. Or we think he has, his work is classified.
Ross got a job at National Physical Laboratory (NPL) in London! Way to go! We will sorely miss Ross, but he leaves behind fantastic work: he first engineered artificial d– and g– waves in colliding Bose-Einstein condensates; as that was …
Spin–orbit coupling links a particle’s velocity to its quantum-mechanical spin, and is essential in numerous condensed matter phenomena, including topological insulators and Majorana fermions. In solid-state materials, spin–orbit coupling originates from the movement of electrons in a crystal’s intrinsic electric …
Karina received her Ph.D. and starts her postdoc in Ching Chin’s group at Chicago. Good luck Karina! In addition to participating in a range of experiments creating artificial gauge fields for cold atoms, Karina: lead our precision experiment measuring the …

We all wish Deep the best in his new Staff Scientist position at the National Physical Laboratory (NPL), New Delhi, India. During his tenure, Deep setup the now operating RbLi experiment on the University of Maryland campus, and lead our …
Interactions between particles can be strongly altered by their environment. We demonstrate a technique for modifying interactions between ultracold atoms by dressing the bare atomic states with light, creating an effective interaction of vastly increased range that scatters states of …
