宇宙系统的量子不确定性

Quantum Indeterminacy of Cosmic Systems

Craig J. Hogan

摘要:

结果表明,在主要由重力控制的系统中,运动的量子不确定性一般随轨道时间尺度$H^{-1}$的增长而增长,并且在距离小于$\approx H^{-3/5}$(普朗克单位)的轨道上主导经典运动。例如,今天的宇宙学度规在宏观距离$H_0^{-3/5}\approx 60$米处变得不确定。估计表明,纠缠的非定域几何量子态和物质可能会显着影响暴胀期间的波动,并连接暗能量的规模与强相互作用。

英文摘要:

It is shown that quantum uncertainty of motion in systems controlled mainly by gravity generally grows with orbital timescale $H^{-1}$, and dominates classical motion for trajectories separated by distances less than $\approx H^{-3/5}$ in Planck units. For example, the cosmological metric today becomes indeterminate at macroscopic separations, $H_0^{-3/5}\approx 60$ meters. Estimates suggest that entangled non-localized quantum states of geometry and matter may significantly affect fluctuations during inflation, and connect the scale of dark energy to that of strong interactions.
