近界面四极跃迁:一般理论及其对平面腔中原子的应用

Quadrupole transitions near interface: general theory and application to atom inside a planar cavity

V. V. Klimov, M. Ducloy

摘要:

用经典和量子电动力学方法研究了任意环境中原子的四极辐射。根据麦克斯韦方程组的格林函数,得到了衰减率的解析表达式。这两种方法的等价性。利用一般表达式分析了处于任意介电常数的两个半空间之间的原子的四极衰变率。结果表明,当原子靠近表面时,总衰变率与原子与界面距离的五次方成反比。

英文摘要:

Quadrupole radiation of an atom in an arbitrary environment is investigated within classical as well as quantum electrodynamical approaches. Analytical expressions for decay rates are obtained in terms of Green function of Maxwell equations. The equivalence of both approaches is shown. General expressions are applied to analyze the quadrupole decay rate of an atom placed between two half spaces with arbitrary dielectric constant. It is shown that in the case when the atom is close to the surface, the total decay rate is inversely proportional to the fifth power of distance between an atom and a plane interface.
