非相对论性QED的重整化电子质量
Renormalized Electron Mass in Nonrelativistic QED
摘要:
在非相对论QED的框架下,我们证明了在耦合常数很小的情况下,修饰电子的能量函数E_ |P|在动量P = 0的邻域内是二次可微的.此外,(E_ |P|)”由大于零的常数从下面界定。我们的结果证明了迭代解析摄动理论的帮助下。
英文摘要:
Within the framework of nonrelativistic QED, we prove that, for small values of the coupling constant, the energy function, E_|P|, of a dressed electron is twice differentiable in the momentum P in a neighborhood of P = 0. Furthermore, (E_|P|)" is bounded from below by a constant larger than zero. Our results are proven with the help of iterative analytic perturbation theory.
