分子飞盘：自旋分子在非均匀场中的运动
Molecular Frisbee: Motion of Spinning Molecules in Inhomogeneous Fields
摘要：
最近提出并证明了几种激光技术用于制备具有盘状角分布的快速自旋态的可极化分子。我们考虑这些旋转盘在不均匀的领域的运动，并表明，分子的轨迹可以精确地控制由激光诱导旋转的平面的倾斜。通过两个延迟的交叉偏振激光脉冲对旋转的线性分子的光学偏转来说明该方案的可行性。这些结果为分子聚焦、导向和捕获等应用开辟了新的途径，并可能适用于光场和静电场分离分子混合物。
英文摘要：
Several laser techniques have been suggested and demonstrated recently for preparing polarizable molecules in rapidly spinning states with a disc-like angular distribution. We consider motion of these spinning discs in inhomogeneous fields, and show that the molecular trajectories may be precisely controlled by the tilt of the plane of the laser-induced rotation. The feasibility of the scheme is illustrated by optical deflection of linear molecules twirled by two delayed cross-polarized laser pulses. These results open new ways for many applications involving molecular focusing, guiding and trapping, and may be suitable for separating molecular mixtures by optical and static fields.
