Inflation at Low Scales: General Analysis and a Detailed Model
William H. Kinney, K. T. Mahanthappa
Models of inflationary cosmology based on spontaneous symmetry breaking typically suffer from the shortcoming that the symmetry breaking scale is driven to nearly the Planck scale…
Inflation From Symmetry Breaking Below the Planck Scale
William H. Kinney, K. T. Mahanthappa
We investigate general scalar field potentials \hbox{} for inflationary cosmology arising from spontaneous symmetry breaking. We find that potentials which are dom…
Composite Gauge fields and Broken Symmetries
B. S. Balakrishna, K. T. Mahanthappa
A generalization of the non-Abelian version of the models (also known as Grassmannian models) is presented. The generalization helps accommodate a partial breaking of th…
Natural Inflation From Fermion Loops
William H. Kinney, K. T. Mahanthappa
``Natural'' inflationary theories are a class of models in which inflation is driven by a pseudo-Nambu-Goldstone boson. In this paper we consider two models, one old and one new, i…
