Non standard scalar field models of inflation and their reheating dynamics

Abstract

The inflationary paradigm which was proposed in the 1980s to solve the so called homogeneity flatness and monopole problems of the big bang theory is now an indispensable part of any study about the origin and evolution of our universe Although a lot of progress has been made in this direction to have a model independent description of inflation from effective theory perspective it is still largely a model dependent phenomena A phase of exponential expansion can be easily achieved by a simpl
