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.
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 …

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 …
