反射微结构附近原子上的延迟Casimir-Polder力

Retarded Casimir-Polder force on an atom near reflecting microstructures

Claudia Eberlein, Robert Zietal

摘要:

我们推导出两种不同几何形状的中性原子的完全延迟的能量位移,用于模拟蚀刻的微结构。首先计算了圆柱形金属丝反射引起的能量位移,然后计算了半无限反射半平面引起的能量位移。我们分析的结果为电线在各种限制的电线半径和原子的距离从电线,并获得简单的渐近表达式有用的估计。对于半平面,我们找到一个精确的表示的Casimir-Polder相互作用的一个单一的,快速收敛的积分,这是很容易评估的数值。

英文摘要:

We derive the fully retarded energy shift of a neutral atom in two different geometries useful for modelling etched microstructures. First we calculate the energy shift due to a reflecting cylindrical wire, and then we work out the energy shift due to a semi-infinite reflecting half-plane. We analyze the results for the wire in various limits of the wire radius and the distance of the atom from the wire, and obtain simple asymptotic expressions useful for estimates. For the half-plane we find an exact representation of the Casimir-Polder interaction in terms of a single, fast converging integral, which is easy to evaluate numerically.
