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 …

Spin–orbit (SO) coupling—the interaction between a quantum particle’s spin and its momentum—is ubiquitous in physical systems. In condensed matter systems, SO coupling is crucial for the spin-Hall effect and topological insulators; it contributes to the electronic properties of materials such …
Yu-Ju Lin who has spent the past three years working on the artificial gauge fields project will be moving on to a permanent position at the Academia Sinica, Taiwan in November. We will miss you, and good luck!
Karina’s paper [Phys. Rev. Lett. 105, 110401 (2010)] featuring a fantastic measurement of the SF/MI phase transition in a 2D Bose-Hubbard system has been published in PRL. Our result is in agreement with QMC calculations with no adjustable parameters. This work …

Ultracold atoms are an excellent system to realize important models in condensed matter physics, owing to its nearly disorder-free and tunable properties. One of the most intriguing topics is the quantum-Hall physics of 2D electronic systems in a strong magnetic …

We experimentally investigate diffraction of a 87Rb Bose-Einstein condensate from a one-dimensional optical lattice. We use a range of lattice periods and timescales, including those beyond the Raman-Nath limit. We compare the results to numerical solutions of the Gross-Pitaevskii equation …
