圆晶格中的衍射和俘获
Diffraction and trapping in circular lattices
摘要：
当单个二能级原子与一对螺旋度相反的拉盖尔-高斯光束相互作用时，这将导致光场与原子之间的角动量有效交换。当径向运动被附加势捕获时，单个局域化原子的波函数可以分裂成沿相反方向旋转的分量。这为无镜脉冲的原子干涉提供了一种新的方案。这种构型的原子也可以被束缚成圆形晶格。
英文摘要：
When a single two-level atom interacts with a pair of Laguerre-Gaussian beams with opposite helicity, this leads to an efficient exchange of angular momentum between the light field and the atom. When the radial motion is trapped by an additional potential, the wave function of a single localized atom can be split into components that rotate in opposite direction. This suggests a novel scheme for atom interferometry without mirror pulses. Also atoms in this configuration can be bound into a circular lattice.
