论文摘要
我们考虑在时空度量的扰动量子波动的情况下，我们考虑了定时的测量一致性。我们计算由于这种波动而导致的一系列大地管的变化，从而获得了量子重新修改的时间型raychaudhuri方程。量子重力通常会增加一致性的收敛性和苛性碱的产生。
We consider a timelike geodesic congruence in the presence of perturbative quantum fluctuations of the spacetime metric. We calculate the change in the volume of a bundle of geodesics due to such fluctuations and thereby obtain a quantum-gravitationally modified timelike Raychaudhuri equation. Quantum gravity generically increases the convergence of congruences and the production of caustics.
