标题： A Quantum Gravity Extension of the Inflationary Scenario

摘要： 由于标准的暴胀范式基于经典时空上的量子场论，它排除了普朗克时代。利用环量子引力的技术，该范式被扩展为一个自洽的理论，从普朗克尺度到慢滚暴胀开始，涵盖了约11个数量级的能量密度和曲率。这种暴胀前的动力学也开辟了一个小窗口，用于新的效应，例如非高斯性的来源，这可能将宇宙学观测的范围扩展到早期宇宙的深层普朗克区域。 显示英文摘要

摘要： Since the standard inflationary paradigm is based on quantum field theory on classical space-times, it excludes the Planck era. Using techniques from loop quantum gravity, the paradigm is extended to a self-consistent theory from the Planck scale to the onset of slow roll inflation, covering some 11 orders of magnitude in energy density and curvature. This pre-inflationary dynamics also opens a small window for novel effects, e.g. a source for non-Gaussianities, which could extend the reach of cosmological observations to the deep Planck regime of the early universe.
