Invariance of cosmological number counts under disformal transformations
Basundhara Ghosh, Jérémie Francfort, Rajeev Kumar Jain
We investigate whether true physical observables associated with the measurements of large scale structure in the universe are frame-independent. In particular, we study if cosmolo…
Leading Gravitational Corrections and a Unified Universe
Alessandro Codello, Rajeev Kumar Jain
Leading order gravitational corrections to the Einstein-Hilbert action can lead to a consistent picture of the universe by unifying the epochs of inflation and dark energy in a sin…
Duality and scale invariant magnetic fields from bouncing universes
Debika Chowdhury, L. Sriramkumar, Rajeev Kumar Jain
Recently, we had numerically shown that, for a non-minimal coupling that is a simple power of the scale factor, scale invariant magnetic fields arise in a class of bouncing univers…
A Unified Universe
Alessandro Codello, Rajeev Kumar Jain
We present a unified evolution of the universe from very early times until the present epoch by including both the leading local correction and the leading non-local term $R\…
On the covariant formalism of the effective field theory of gravity and leading order corrections
Alessandro Codello, Rajeev Kumar Jain
We construct the covariant effective field theory of gravity as an expansion in inverse powers of the Planck mass, identifying the leading and next-to-leading quantum corrections.…
