退相干与红外发散
Decoherence and infrared divergence
摘要：
研究了与玻色子场线性耦合的粒子动力学。如果玻色子场是红外发散的，那么玻色子场会导致粒子动量的超选择规则。因此，整个系统的哈密顿量从下面保持有界。
英文摘要：
The dynamics of a particle which is linearly coupled to a boson field is investigated. The boson field induces superselection rules for the momentum of the particle, if the field is infrared divergent. Thereby the Hamiltonian of the total system remains bounded from below.
