Gauge fields are central in our modern understanding of physics at all scales. At the highest energy scales known, the microscopic universe is governed by particles interacting with each other through the exchange of gauge bosons. At the largest length …
The ICAP 2014 Summer School held at The College of William and Mary in Williamsburg, VA was a great success with about 100 students attending the 18 lectures given by our fantastic speakers. Follow this link for lecture notes and …

We explore the time evolution of two-component Bose-Einstein condensates (BECs), quasi one dimensional with respect to their spinor dynamics, following a quench from one component BECs with a U(1) order parameter into two-component condensates with a U(1)xZ2 order parameter. In …

We describe a simple technique for generating a cold-atom lattice pierced by a uniform magnetic field. Our method is to extend a one-dimensional optical lattice into the “dimension” provided by the internal atomic degrees of freedom, yielding a synthetic two-dimensional …
Group alumna Yu-Ju Lin visited from Feb. 10 to Feb. 14! In the key-picture you see Yu-Ju along with Lauren and Dina in the lab where Yu-Ju executed our fantastic experiments with synthetic magnetic fields and for the first time …
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 …
