我们提出了一个实验，直接探测非阿贝尔统计的马约拉纳费米子编织它们在s波超流体的超冷原子。我们表明，不同的订单的编织操作给出了正交的输出状态，可以通过拉曼光谱区分。在s波超流体中实现Majorana态需要强的自旋轨道耦合和垂直方向的可控塞曼场。我们提出了一个简单的激光配置，以产生人工自旋轨道耦合和所需的塞曼场的暗态子空间。
We propose an experiment to directly probe the non-abelian statistics of Majorana fermions by braiding them in an s-wave superfluid of ultracold atoms. We show that different orders of braiding operations give orthogonal output states that can be distinguished through Raman spectroscopy. Realization of Majorana states in an s-wave superfluid requires strong spin-orbital coupling and a controllable Zeeman field in the perpendicular direction. We present a simple laser configuration to generate the artificial spin-orbital coupling and the required Zeeman field in the dark-state subspace.
