Abstract

Spin-orbit coupling is an essential ingredient in topological materials, conventional and quantum-gas-based alike. Engineered spin-orbit coupling in ultracold-atom systems—unique in their experimental control and measurement opportunities—provides a major opportunity to investigate and understand topological phenomena. Here we experimentally demonstrate and theoretically analyze a technique for controlling spin-orbit coupling in a two-component Bose-Einstein condensate using amplitude-modulated Raman coupling.

On-Demand Spin-Orbit Coupling

Published 24 March 2015

Laser-induced spin-orbit coupling in ultracold atoms can be tuned, in contrast to the fixed spin-orbit coupling in materials like topological insulators.
