干涉仪中量子引力的观测特征

Observational Signatures of Quantum Gravity in Interferometers

Erik P. Verlinde, Kathryn M. Zurek

摘要:

我们考虑的不确定性的干涉仪的臂长由于度量波动的量子引力的性质,提出了一个具体的微观模型的能量波动的全息自由度的表面上的因果连接的时空区域的边界。在我们的模型中,波动纵向光束方向积累在红外和功能强大的长距离相关的横向方向。这就产生了一个可以在引力波干涉仪中观察到的信号。我们将计算中的位置不确定原理与特胡夫特引力S矩阵联系起来。

英文摘要:

We consider the uncertainty in the arm length of an interferometer due to metric fluctuations from the quantum nature of gravity, proposing a concrete microscopic model of energy fluctuations in holographic degrees of freedom on the surface bounding a causally connected region of spacetime. In our model, fluctuations longitudinal to the beam direction accumulate in the infrared and feature strong long distance correlation in the transverse direction. This leads to a signal that could be observed in a gravitational wave interferometer. We connect the positional uncertainty principle arising from our calculations to the 't Hooft gravitational S-matrix.
