提出了一种具有量子引力起源动态尺度的新颖原初谱来解释 COBE 和 WMAP 观测中低多极点处角功率谱的急剧下降。该光谱源自诱导重力可重整模型中标量曲率的量子涨落。该模型通过围绕暴胀背景波动的共形场和普朗克质量级的膨胀时间常数来描述非常早期的宇宙。
A novel primordial spectrum with a dynamical scale of quantum gravity origin is proposed to explain the sharp fall off of the angular power spectra at low multipoles in the COBE and WMAP observations. The spectrum is derived from quantum fluctuations of the scalar curvature in a renormalizable model of induced gravity. This model describes the very early universe by the conformal field fluctuating about an inflationary background with the expansion time constant of order of the Planck mass.
