Direct imaging of topological edge states in cold-atom systems
N. Goldman, J. Dalibard, A. Dauphin +4
Detecting topological order in cold-atom experiments is an ongoing challenge, the resolution of which offers novel perspectives on topological matter. In material systems, unambigu…
Measuring topology in a laser-coupled honeycomb lattice: From Chern insulators to topological semi-metals
N. Goldman, E. Anisimovas, F. Gerbier +3
Ultracold fermions trapped in a honeycomb optical lattice constitute a versatile setup to experimentally realize the Haldane model [Phys. Rev. Lett. 61, 2015 (1988)]. In this syste…
Flux lattices reformulated
G. Juzeliūnas, I. B. Spielman
We theoretically explore the optical flux lattices produced for ultra-cold atoms subject to laser fields where both the atom-light coupling and the effective detuning are spatially…
Dynamically Slowed Collapse of a Bose-Einstein Condensate with Negative Scattering Length
R. L. Compton, Y. -J. Lin, K. Jimenez-Garcia +2
We rapidly change the scattering length a_s of a 87Rb Bose-Einstein condensate by means of a Feshbach resonance, simultaneously releasing the condensate from its harmonic trapping…
