Karina and Ian’s book chapter on Mott/Superfluid physics published

Karina and Ian’s book chapter “The Mott Transition in a Bose Gas Measured Through Time of Flight” is published on page 145 of the “Annual Reviews of Cold atoms and Molecules” volume 2.  Wow, it takes a long time for

Zitterbewegung featured as a NJP “Highlight of 2013”

Lindsay LeBlanc et al‘s result demonstrating Zitterbewegung in a spin-orbit coupled atomic Bose gas has been featured as a “Highlight of 2013” by The New Journal of Physics!  Way to go team! Highlights page: Article:

Zitterbewegung: JQI writeup

S. Kelly of the JQI did a very nice writeup with awesome artwork for Lindsay’s Zitterbewegung paper as follows: In “Harry Potter and the Sorcerer’s Stone” (JK Rowling, 1997), Harry, Ron, and Hermione encounter a massive stone chessboard, one of many

Raman-Induced Interactions in a Single-Component Fermi Gas Near an s-Wave Feshbach Resonance

Ultracold gases of interacting spin-orbit-coupled fermions are predicted to display exotic phenomena such as topological superfluidity and its associated Majorana fermions. Here, we experimentally demonstrate a route to strongly interacting single-component atomic Fermi gases by combining an s-wave Feshbach resonance (giving

Lindsay LeBlanc starts at the University of Alberta, Edmonton

We all wish Lindsay the best as she moves on to her new Assistant Professor position at the University of Alberta, Edmonton!  In her time in the group, Linsday lead two fantastically successful experiments, first measuring the Hall effect in a

Direct observation of zitterbewegung in a Bose–Einstein condensate

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

Karina Jimenéz-García is a finalist for the 2013 DAMOP thesis prize!

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.

The spin Hall effect in a quantum gas

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 moves on. Permanently.

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 Jimenéz-García graduates and moves on to a postdoc!

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
