我们在宏观量子电动力学的框架内研究了原子与一维纳米光栅的相互作用，特别强调了可能的各向异性贡献。为此，我们首先推导出散射绿色的光栅的瑞利展开的手段张量，并讨论其对称性和渐近线。然后我们用光栅确定了原子的Casimir-Polder势。特别是，我们发现，强各向异性可以导致一个排斥Casimir-Polder势在正常方向。
We study the interaction of an atom with a one-dimensional nano-grating within the framework of macroscopic QED, with special emphasis on possible anisotropic contributions. To this end, we first derive the scattering Green's tensor of the grating by means of a Rayleigh expansion and discuss its symmetry properties and asymptotes. We then determine the Casimir--Polder potential of an atom with the grating. In particular, we find that strong anisotropy can lead to a repulsive Casimir--Polder potential in the normal direction.
