干涉仪对地转脉动的响应

Interferometer Response to Geontropic Fluctuations

Dongjun Li, Vincent S. H. Lee, Yanbei Chen, Kathryn M. Zurek

摘要:

我们在量子引力中用一个高占据数的标量场来模拟真空涨落。标量的占据数由热密度矩阵给出,其形式是由真空能量的波动激发的,这已经被证明是共形的光片视界附近。对于干涉仪中感兴趣的实验测量,能量波动的大小由限定被干涉仪询问的时空体积的表面的面积固定。我们计算干涉仪响应这些“geontropic”标量度量波动,并将我们的结果应用到当前和未来的干涉仪测量,如LIGO和建议的GQuEST实验。

英文摘要:

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.
