标题： Observational effects from quantum cosmology

摘要： 量子宇宙学作为早期宇宙的可检验模型的地位在暴胀的背景下得到评估。 尽管传统的惠勒-德维特量子化无法在宇宙微波背景中产生显著效应，但最近的圈量子宇宙学可以产生可能被检测到的标准宇宙谱的偏离。 因此，目前的观测限制了该模型的参数空间，这可以通过未来不久的实验使其变得可证伪。 显示英文摘要

摘要： The status of quantum cosmologies as testable models of the early universe is assessed in the context of inflation. While traditional Wheeler-DeWitt quantization is unable to produce sizable effects in the cosmic microwave background, the more recent loop quantum cosmology can generate potentially detectable departures from the standard cosmic spectrum. Thus, present observations constrain the parameter space of the model, which could be made falsifiable by near-future experiments.
