Título: | Observational effects from quantum cosmology |
Autor: | Calcagni, Gianluca CSIC ORCID | Palabras clave: | Loop quantum cosmology Inflation Quantum cosmology |
Fecha de publicación: | 2013 | Editor: | Wiley-VCH | Citación: | Annalen der Physik (Leipzig) 525: 323- 338 (2013) | Resumen: | 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.
