全息泡沫宇宙学:从晚期到早期宇宙

Holographic Foam Cosmology: From the Late to the Early Universe

Y. Jack Ng

摘要:

量子涨落赋予时空一种泡沫质地。泡沫的程度是由黑洞物理决定的,是全息类型的。应用于宇宙学,全息泡沫模型预测了在当前(晚期)宇宙中存在具有临界能量密度的暗能量,其量子服从无穷统计。此外,我们利用湍流和强量子引力的时空泡沫相之间的深刻相似性来论证早期宇宙在经历短暂的宇宙暴胀时处于湍流状态,并“优雅”地过渡到层流状态。在这种情况下,晚期和早期的宇宙加速都起源于时空泡沫。

英文摘要:

Quantum fluctuations endow spacetime with a foamy texture. The degree of foaminess is dictated by blackhole physics to be of the holographic type. Applied to cosmology, the holographic foam model predicts the existence of dark energy with critical energy density in the current (late) universe, the quanta of which obey infinite statistics. Furthermore we use the deep similarities between turbulence and the spacetime foam phase of strong quantum gravity to argue that the early universe was in a turbulent regime when it underwent a brief cosmic inflation with a "graceful" transition to a laminar regime. In this scenario, both the late and the early cosmic accelerations have their origins in spacetime foam.
