我们研究了两个量子力学振荡器系统模型的动力学，该模型是由截断到零空间维度的线性化重力耦合到大质量标量场和标量量子电动力学（QED）得到的。标量-重力玩具模型映射到相位阻尼振荡器，而标量QED玩具模型近似映射到受双光子阻尼的振荡器系统。玩具模型为解决与全标量QED和弱引力场系统相关的开放系统量子动力学提供了潜在的有用见解，特别是对初始标量场系统叠加态的退相干的操作探测。
We investigate the dynamics of two quantum mechanical oscillator system–bath toy models obtained by truncating to zero spatial dimensions linearized gravity coupled to a massive scalar field and scalar quantum electrodynamics (QED). The scalar-gravity toy model maps onto the phase damped oscillator, while the scalar QED toy model approximately maps onto an oscillator system subject to two-photon damping. The toy models provide potentially useful insights into solving for open system quantum dynamics relevant to the full scalar QED and weak gravitational field systems, in particular operational probes of the decoherence for initial scalar field system superposition states.
