Species-specific optical lattices
We examine single-frequency optical schemes for species-selective trapping of ultracold alkali-metal atoms. Independently addressing the elements of a binary mixture enables the creation of an…
Synthetic Partial Waves in Ultracold Atomic Collisions
A pair of Raman lasers are used to modify the interaction between two colliding Bose-Einstein condensates to include beyond–s-wave (d- and g-wave) contributions, expected to enable quantum simulation of exotic systems, including those predicted to support Majorana fermions.
Dynamics of a tunable superfluid junction.
The population dynamics of a Bose-Einstein condensate in a double-well potential throughout the crossover from Josephson dynamics to hydrodynamics is studied and implications for trapped matter-wave interferometers are discussed.

Electromagnetically induced transparency (EIT) and Autler-Townes splitting (ATS) are similar,but different quantum optical phenomena: EIT results from a Fano interference, whereas ATS is described by…

A one-dimensional lattice derived purely from effective Zeeman shifts resulting from a combination of Raman coupling and radio-frequency magnetic fields is described, with experimentally realizing the Peierls substitution for ultracold neutral atoms.
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…

This work experimentally demonstrates a route to strongly interacting single-component atomic Fermi gases by combining an s-wave Feshbach resonance (giving strong interactions) and spin-orbit coupling (creating an effective p-wave channel).
Rapid sympathetic cooling to Fermi degeneracy on a chip
Neutral fermions present new opportunities for testing models of many-body quantum systems, realizing precision atom interferometry, producing ultra-cold molecules, and investigating fundamental…
Tunable spin-orbit coupling via strong driving in ultracold-atom systems.
A technique for controlling spin-orbit coupling in a two-component Bose-Einstein condensate using amplitude-modulated Raman coupling is experimentally demonstrated and theoretically analyzed.
