我们提出了描述标量玻色子场与外部弱随机引力场相互作用的量子动力学的一般主方程。动力学预测了位置和能量动量的退相干。我们展示了主方程如何通过采取适当的极限来再现，从而推广文献中先前的结果。我们估计了原子干涉仪中引力退相干的影响，也提供了一种直接的方法来评估影响的大小。
We present a general master equation describing the quantum dynamics of a scalar bosonic field interacting with an external weak and stochastic gravitational field. The dynamics predicts decoherence both in position and in energy momentum. We show how the master equation reproduces, thus generalizing, the previous results in the literature by taking appropriate limits. We estimate the effect of gravitational decoherence in atom interferometers, providing also a straightforward way to assess the magnitude of the effect.
