摘要: We demonstrate submicron spatial control of interatomic interactions in a Bose-Einstein condensate ytterbium (Yb). A pulsed optical standing wave, tuned near an Feshbach resonance, varies the s-wave scattering length continuously across wave pattern. The modulated mean-field energy with period every 278 nm is monitored by diffraction pattern time-of-flight image. observe wide up to 250 nm. demonstrated modulation proves that high resolution atomic possible.
