研究了带电粒子与量子化紫外截止辐射场相互作用的各种模型。上限和下限的自我或基态能量没有质量重整化。对于N费米子，边界与N成正比，但对于玻色子，它们是次线性的，这意味着“束缚”，因此“自由”玻色子永远不会自由。“相对论”和非相对论运动学被认为是。我们的边界是非微扰的，并显着不同于微扰理论的预测。
Various models of charged particles interacting with a quantized, ultraviolet cutoff radiation field (but not with each other) are investigated. Upper and lower bounds are found for the self- or ground state-energies without mass renormalization. ForNfermions the bounds are proportional toN, but for bosons they are sublinear, which implies ‘binding’, and hence that ‘free’ bosons are never free. Both ‘relativistic’ and non-relativistic kinematics are considered. Our bounds are non-perturbative and differ significantly from the predictions of perturbation theory.
