The equilibrium properties of an open harmonic oscillator are considered in three steps: first the creation and destruction operators are generalized for open dynamics and the creation operator is used to construct coherent states. The second step consists of the introduction of the Heisenberg representation where the dynamical decoherence is identified. Finally it is pointed out that the quantum fluctuations generate non-continuous limit for infinitesimal system–environment interactions and at the border of the under- and over-damped oscillator.

开谐振荡器的平衡特性和去相干

分三步考虑开放谐波振荡器的平衡特性:首先将生成和破坏算子推广用于开放动力学,然后使用生成算子构建相干态。第二步包括引入海森堡表示法,其中可以识别动态退相干。最后要指出的是,量子涨落产生了无限小的系统-环境相互作用的非连续极限,并且在欠阻尼和过阻尼振荡器的边界。
