关于哈密顿量作为聚合参数的注记

A note on the Hamiltonian as a polymerisation parameter

Norbert Bodendorfer, Fabio M. Mele, Johannes Münch

摘要:

在回路量子引力的有效模型中,量子效应的开始由所谓的聚合尺度控制。为了获得合理的物理学,有时需要使该尺度相空间相关。最近用来研究量子修正的黑洞时空的一个特别有趣的选择,是用时间平移的发生器本身来设定尺度。我们回顾这一想法,指出最近的治疗中的错误,并说明如何在原则上修复它们。

英文摘要:

In effective models of loop quantum gravity, the onset of quantum effects is controlled by a so-called polymerisation scale. It is sometimes necessary to make this scale phase space dependent in order to obtain sensible physics. A particularly interesting choice recently used to study quantum corrected black hole spacetimes takes the generator of time translations itself to set the scale. We review this idea, point out errors in recent treatments, and show how to fix them in principle.
