Scalaron tunneling and the fate of antisymmetric tensor fields in F(R) gravity

The work provides a possible explanation of a well motivated question—why the present Universe is practically free from any noticeable footmarks of higher rank antisymmetric tensor fields, despite…

Cosmology in multiply warped braneworld scenario

Hubble expansion in warped braneworld model is addressed in the presence of more than one warped extra dimensions. Some distinct phenomenological signatures of such model has already been discussed…

Antisymmetric Tensor Fields in Modified Gravity: A Summary

The Kalb–Ramond field has a significant contribution during early universe; in particular, it affects the beginning of inflation as well as increases the amount of primordial gravitational radiation and hence enlarges the value of tensor-to-scalar ratio in the case when the KR field is absent.

Inflationary universe in F(R) gravity with antisymmetric tensor fields and their suppression during its evolution

The intriguing question, why the present scale of the universe is free from any perceptible footprints of rank-2 antisymmetric tensor fields? (generally known as Kalb-Ramond fields) is addressed. A…

Features of warped geometry in presence of Gauss-Bonnet coupling

A bstractWe study the role of the Gauss-Bonnet corrections and two loop higher genus contribution to the gravity action on the Kaluza-Klien modes and their interactions for different bulk fields…

We study the role of the Gauss-Bonnet corrections and two loop higher genus contribution to the gravity action on the Kaluza-Klien modes and their interactions for different bulk fields which enable…

Periodic thick-brane configurations and their stability

I investigate models with scalar fields in five dimensions that exhibit thick-brane configurations with a non-trivial metric. I show that an appropriate coupling to the scalar curvature allows for…

Dynamical suppression of spacetime torsion

A surprising feature of our present four dimensional universe is that its evolution appears to be governed solely by spacetime curvature without any noticeable effect of spacetime torsion. In the…

Bulk antisymmetric tensor fields in a Randall-Sundrum model

We consider bulk antisymmetric tensor fields of various ranks in a Randall-Sundrum scenario. We show that, rank 2 onwards, the zero-modes of the projections of these fields on the (3+1)-dimensional…

Bulk fields in the Randall-Sundrum compactification scenario

Recently, Randall and Sundrum proposed a solution to the hierarchy problem where the background spacetime is five dimensional. There are two 3-branes, and the mass scale for fields that propagate on…

Gravitational redshift in Einstein-Kalb-Ramond spacetime and Randall-Sundrum scenario

It is shown that the gravitational redshift as predicted by Einstein's theory is modified in the presence of a second-rank antisymmetric tensor (Kalb-Ramond) field in a string-inspired background…

Does a randall-sundrum scenario create the illusion of a torsion-free universe?

This work considers spacetime with torsion in a Randall-Sundrum scenario where torson, identified with the rank-2 Kalb-Ramond field, exists in the bulk together with gravity and finds that an additional exponential suppression comes for the torsions zero-mode on the visible brane.

We present gravitational aspects of braneworld models endowed with torsion terms both in the bulk and on the brane. In order to investigate a conceivable and measurable gravitational effect, arising…

Phenomenology of the randall-sundrum gauge hierarchy model
