我们研究了一个电偶极矩不为零的中性原子与量子化电磁场的耦合。对于足够小的偶极矩和小动量p→，证明了原子的单粒子(自)能是其动量的实解析函数。我们证明的主要内容是Feshbach-Schur谱重整化群的一个合适的形式。
We study a neutral atom with a non-vanishing electric dipole moment coupled to the quantized electromagnetic field. For a sufficiently small dipole moment and small momentum, p→, the one-particle (self-) energy of an atom is proven to be a real-analytic function of its momentum. The main ingredient of our proof is a suitable form of the Feshbach–Schur spectral renormalization group.
