从Wheeler-De Witt方程的修正看暗能量存在的可能性

On the possibility of Dark Energy from corrections to the Wheeler-De Witt equation

William Nelson, Mairi Sakellariadou

摘要:

本文提出了一种近似Wheeler-DeWitt方程的一般量子引力修正的有效结果的方法。我们表明,在许多情况下,这些修正可以产生偏离经典物理在大尺度上,这种行为可以被解释为额外的物质成分。这开启了一种可能性,即暗能量(以及可能的暗物质)可能是量子引力对经典广义相对论的修正的大尺度表现。作为一个具体的例子,我们研究一阶修正的惠勒-德威特方程所产生的循环量子宇宙学的晶格细化的情况下,并显示如何在大尺度物理的最终崩溃发生。

英文摘要:

We present a method for approximating the effective consequence of generic quantum gravity corrections to the Wheeler-DeWitt equation. We show that in many cases these corrections can produce departures from classical physics at large scales and that this behaviour can be interpreted as additional matter components. This opens up the possibility that dark energy (and possible dark matter) could be large scale manifestations of quantum gravity corrections to classical general relativity. As a specific example we examine the first order corrections to the Wheeler-De Witt equation arising from loop quantum cosmology in the absence of lattice refinement and show how the ultimate breakdown in large scale physics occurs.
