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…
