论文摘要
我们用标量场对量子重力的真空波动进行建模，其特征是高职业数量，并耦合到度量标准。标量的职业数量是由热密度矩阵给出的，其形式是由真空能量波动的动机，已证明在浅色表层附近是保形的。对于在干涉仪中的实验测量，能量波动的大小是由界定空间体积的面积固定的，该空间的体积被干涉仪询问。我们计算了对这些“地球形”标量值波动的干涉仪响应，并将结果应用于当前和将来的干涉仪测量值，例如Ligo和拟议的GQUEST实验。
We model vacuum fluctuations in quantum gravity with a scalar field, characterized by a high occupation number, coupled to the metric. The occupation number of the scalar is given by a thermal density matrix, whose form is motivated by fluctuations in the vacuum energy, which have been shown to be conformal near a light-sheet horizon. For the experimental measurement of interest in an interferometer, the size of the energy fluctuations is fixed by the area of a surface bounding the volume of spacetime being interrogated by an interferometer. We compute the interferometer response to these "geontropic" scalar-metric fluctuations, and apply our results to current and future interferometer measurements, such as LIGO and the proposed GQuEST experiment.
