米尔本最近提出了[Phys。 Rev. A 44, 5401 (1991)]薛定谔方程的一种变体，它模拟系统通过超越传统量子力学的内在机制而不是与环境的耗散相互作用演化时的退相干。在本文中，我们给出了该方程的精确解，并将其应用于具有非平凡动力学的原子场相互作用的 Jaynes-Cummings 模型。我们证明，内在的退相干性是导致该模型中量子相干效应恶化的原因，例如原子反转的复兴。我们讨论米尔本方程的适用性
Milburn has recently proposed [Phys. Rev. A 44, 5401 (1991)] a variation of the Schrodinger equation which models decoherence as the system evolves through intrinsic mechanisms beyond conventional quantum mechanics rather than dissipative interaction with an environment. In this paper we give an exact solution of this equation and apply it to the Jaynes-Cummings model of atom-field interaction with nontrivial dynamics. We show that the intrinsic decoherence is responsible for deterioration of quantum coherence effects in this model, such as revivals of the atomic inversion. We discuss the applicability of the Milburn equation
