摘要。带电粒子与量子化电磁场和外部电位相互作用的激发态都会衰减，但这样的粒子应该有一个真正的基态——一个能量最小并满足Schrödinger方程的基态。我们相当普遍地证明，这种状态对于所有的精细结构常数和紫外截止值都存在。我们也展示了在物理自然条件下的多粒子系统。
Abstract.The excited states of a charged particle interacting with the quantized electromagnetic field and an external potential all decay, but such a particle should have a true ground state – one that minimizes the energy and satisfies the Schrödinger equation. We prove quite generally that this state exists for all values of the fine-structure constant and the ultraviolet cutoff. We also show the same thing for a many-particle system under physically natural conditions.
