Resonant absorption imaging is a common technique for detecting the two-dimensional column density of ultracold atom systems. In many cases, the system’s thickness along the imaging direction greatly exceeds the imaging system’s depth of field, making the identification of the …

Much of the old RbII team traveled to San Crístobal de las Casas, Mexico to attend the wedding of Karina (the happy one on the left) and Neil (the lucky one on the right), formerly of the RbII team (Karina) …
Third year review on Dec. 12-13 the atomtronics MURI, and like with last year the review will be a 1.5 day event. Approximate times: starting at 1:00 PM on the 12th, and ending at 5PM on the 13th. The location …
The third year review for the Atomtronics MURI has been postponed. Stay tuned.
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 …
We present a new technique for producing two- and three-dimensional Rashba-type spin-orbit couplings for ultracold atoms without involving light. The method relies on a sequence of pulsed inhomogeneous magnetic fields imprinting suitable phase gradients on the atoms. For sufficiently short …

Third year review on Oct. 9-10 the atomtronics MURI, and like with last year the review will be a 1.5 day event. Approximate times: starting at 1:00 PM on the 9th, and ending at 5PM on the 10th. The location …
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 …
We investigate the properties of an atom under the influence of a synthetic three-dimensional spin–orbit coupling (Weyl coupling) in the presence of a harmonic trap. The conservation of total angular momentum provides a numerically efficient scheme for finding the spectrum …
Creating and measuring topological matter – with non-local order deeply embedded in the global structure of its quantum mechanical eigenstates – presents unique experimental challenges. Since this order has no signature in local correlation functions, it might seem experimentally inaccessible …
