Improving Slow-Roll Estimates in Starobinsky Inflation Using an Analytic Hubble Parameter
Jose Mathew
Inflationary observables are naturally formulated in terms of the Hubble-flow hierarchy. Because exact background solutions are often unavailable, the Hubble-flow parameters are co…
Infinitely degenerate exact Ricci-flat solutions in f(R) gravity
Semin Xavier, Jose Mathew, S. Shankaranarayanan
We obtain an infinite number of exact static, Ricci-flat spherically symmetric vacuum solutions for a class of f(R) theories of gravity. We analytically derive two exact vacuum bla…
Bounce inflation driven by Higgs field
Jose Mathew
In this work, we investigate a model of bounce inflation driven by the Higgs field. The Higgs field is non-minimally coupled with gravity through the Gauss-Bonnet term. We show tha…
Exact inflationary solutions in exponential gravity
Joseph P Johnson, Jose Mathew, S. Shankaranarayanan
We consider a modified gravity model of the form , where the strong gravity corrections are taken to all orders and is a self-interacting massless scalar…
Inflation with in Jordan frame
Jose Mathew, Joseph P Johnson, S. Shankaranarayanan
We consider an action that is non-minimally coupled to a massive scalar field. The model closely resembles scalar-tensor theory and by conformal transformation can be transf…
Low Scale Higgs Inflation with Gauss-Bonnet Coupling
Jose Mathew, S. Shankaranarayanan
Recent LHC data provides precise values of coupling constants of the Higgs field, however, these measurements do not determine its coupling with gravity. We explore this freedom to…
