Iso-spectral potential and inflationary quantum cosmology
arXiv:gr-qc/0606123 · doi:10.1007/s10773-006-9216-y
Abstract
Using the factorization approach of quantum mechanics, we obtain a family of isospectral scalar potentials for power law inflationary cosmology. The construction is based on a scattering Wheeler-DeWitt solution. These iso-spectrals have new features, they give a mechanism to end inflation, as well as the possibility to have new inflationary epochs. The procedure can be extended to other cosmological models.
