A direct classical analog of quantum decoherence is introduced. Similarities and differences between decoherence dynamics examined quantum mechanically and classically are exposed via a second-order perturbative treatment and via a strong decoherence theory, showing a strong dependence on the nature of the system-environment coupling. For example, for the traditionally assumed linear coupling, the classical and quantum results are shown to be in exact agreement.
引入了量子退相干的直接经典类似物。通过二阶微扰处理和强退相干理论揭示了量子力学和经典方式下退相干动力学之间的异同，表明其强烈依赖于系统 - 环境耦合的性质。例如，对于传统假设的线性耦合，经典结果和量子结果显示完全一致。
