论文摘要
现在，制作具有足够长寿命和足够低疾病的北极子的玻色网凝结物是常规的，可以在准二维（1D）电线中弹弹弹性。我们介绍了在一个准1D环上注入一个点的偏振子冷凝物，其初始速度和方向有明确的初始速度和方向。可以看到圆形极化的明显进动，这是由于哈密顿量中有效的自旋轨道耦合术语引起的。我们的理论模型准确地预测了实验观察到的行为，并表明“ Zitterbewegung”行为在极化子的运动中起作用。
It is now routine to make Bose-Einstein condensates of polaritons with long enough lifetime and low enough disorder to travel ballistically for hundreds of microns in quasi-one-dimensional (1D) wires. We present observations of a polariton condensate injected at one point in a quasi-1D ring, with a well-defined initial velocity and direction. A clear precession of the circular polarization is seen, which arises from an effective spin-orbit coupling term in the Hamiltonian. Our theoretical model accurately predicts the experimentally observed behavior, and shows that "zitterbewegung" behavior plays a role in the motion of the polaritons.
