标题： Spacetime foam

摘要： 时空由称为时空泡沫或量子泡沫的波动排列的气泡或环组成。 我们利用全息原理推导其结构，并表明结果与涉及时空测量的思想实验一致。 我们提出使用基于激光的原子干涉测量技术来寻找时空波动。 我们的分析明确表明，量子泡沫的物理与黑洞的物理密不可分。 因此，负面的实验结果可能对半经典引力和黑洞物理产生非平凡的影响。 显示英文摘要

摘要： Spacetime is composed of a fluctuating arrangement of bubbles or loops called spacetime foam, or quantum foam. We use the holographic principle to deduce its structure, and show that the result is consistent with gedanken experiments involving spacetime measurements. We propose to use laser-based atom interferometry techniques to look for spacetime fluctuations. Our analysis makes it clear that the physics of quantum foam is inextricably linked to that of black holes. A negative experimental result, therefore, might have non-trivial ramifications for semiclassical gravity and black hole physics.
