Slow-roll approximation in loop quantum cosmology - IOPscience

Webb26 okt. 2000 · Inflationary predictions for the anisotropy of the cosmic microwave background radiation are often based on the slow-roll approximation. We study the … Webb1 okt. 2024 · Slow roll inflation requires that the effective inflaton mass should be much smaller than the Hubble parameter during inflation, that is m2 ≪ H2. However, when we try to build an inflation model in the framework of string theory or supergravity, one often encounter an Hubble induced inflaton mass, that is m2 ∼ H2[1], [2]. two cabins lodge
