Tunable Spin-Orbit Coupling via Strong Driving in Ultracold Atom Systems



Ian B. Spielman, Lindsay J. LeBlanc, Ross A. Williams, Matthew C. Beeler, Chunlei Qu, Ming Gong, Chuanwei Zhang


Spin-orbit coupling (SOC) 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 SOC in a two component Bose-Einstein condensate using amplitude modulated Raman coupling.
