Abstract

The free electron spin dynamics in Kapitza–Dirac (KD) effect had been studied theoretically in one-dimensional standing wave of EUV to X-ray laser with extremely high intensity, which is far beyond experimental realization. Here, we propose to achieve the free electron spin-dependent KD effect in two-dimensional triangular optical lattice with spatial inversion symmetry breaking, and the theoretical results reveal that laser with wavelength in visible or near-IR and five orders of magnitude decreased intensity could lead to obvious spin-dependent KD effect. This work provides the way to realize the free electron spin-dependent KD effect experimentally.

二维三角形光晶格中自由电子自旋依赖的卡皮查-迪拉克效应

在一维驻波的极高强度的EUV到X射线激光中，对Kapitza-Dirac（KD）效应中的自由电子自旋动力学进行了理论研究，这远远超出了实验实现的范围。在这里，我们提出在二维三角形光晶格中实现空间反转对称破缺的自由电子自旋依赖 KD 效应，理论结果表明，波长在可见光或近红外、强度降低五个数量级的激光可以导致明显的自旋依赖 KD 效应。这项工作为在实验中实现自由电子自旋依赖的 KD 效应提供了途径。
