Our paper on "ultrafast spinor matterwave gate" with off resonant Raman pulses, in collaboration with Prof. Yuan Haidong, is finally on arXiv! This work is based on Liyang's PhD work but there have been various conceptual developments afterward. Speical thanks to Jiangyong, who is now in charge of experimental progresses, for various discussions. Let's now see how we put the idea into run!
