Tensor Perturbations from Bounce Inflation Scenario in f(Q) Gravity
Kun Hu, Tanmoy Paul, Taotao Qiu
In this paper, we construct a bounce inflation cosmological scenario in the framework of the modified symmetric teleparallel gravity, namely f(Q) theory, and investigate the tensor…
Effective Theory of Inflationary Magnetogenesis and Constraints on Reheating
Debaprasad Maity, Sourav Pal, Tanmoy Paul
Effective theory framework based on symmetry has recently gained widespread interest in the field of cosmology. In this paper, we apply the same idea on the genesis of the primordi…
Invisibility of antisymmetric tensor fields in the light of gravity
Ashmita Das, Tanmoy Paul, Soumitra SenGupta
A natural question arises from observable signatures of scalar, fermion, and vector degrees of freedom (d.o.f.) in our Universe along with spin 2 symmetric tensor field in the form…
A possible testbed for warped extra dimension from the angle of Buchdahl's limit
Tanmoy Paul
We consider a five dimensional AdS warped spacetime in presence of a massive scalar field in the bulk. The scalar field potential fulfills the requirement of modulus stabilization…
Radion tunneling in modified theories of gravity
Tanmoy Paul, Soumitra SenGupta
We consider a five dimensional warped spacetime where the bulk geometry is governed by higher curvature gravity. In this model, we determine the modulus potential originatin…
Scalar field collapse in Gauss-Bonnet gravity
Narayan Banerjee, Tanmoy Paul
We consider a "Scalar-Einstein-Gauss-Bonnet" theory in four dimension, where the scalar field couples non minimally with the Gauss-Bonnet (GB) term. This coupling with the scalar f…
Fermion localization in higher curvature and scalar-tensor theories of gravity
Joydip Mitra, Tanmoy Paul, Soumitra SenGupta
It is well known that in a braneworld model, the localization of fermions on lower dimensional submanifold (say a TeV 3-brane) is governed by the gravity in the bulk which also det…
Bouncing cosmology from warped extra dimensional scenario
Ashmita Das, Debaprasad Maity, Tanmoy Paul +1
From the perspective of four dimensional effective theory on a two brane warped geometry model, we examine the possibility of "bouncing phenomena"on our visible brane. Our results…
Inflationary scenario from higher curvature warped spacetime
Narayan Banerjee, Tanmoy Paul
We consider a five dimensional AdS spacetime, in presence of higher curvature term like in the bulk, in the context of Randall-Sundrum two-brane model. Our univer…
Fermion localization in a backreacted warped spacetime
Tanmoy Paul, Soumitra SenGupta
We consider a five dimensional AdS warped spacetime in presence of a massive scalar field in the bulk. The scalar field potential fulfills the requirement of modulus stabilization…
"Brane localized energy density" stabilizes the modulus in higher dimensional warped spacetime
Tanmoy Paul
We consider a five dimensional AdS spacetime with two 3-brane scenario where the hidden brane contains a certain amount of positive constant energy density. In this model, we exami…
Radion stabilization in higher curvature warped spacetime
Ashmita Das, Hiya Mukherjee, Tanmoy Paul +1
We consider a five dimensional AdS spacetime in presence of higher curvature term like in the bulk. In this model, we examine the possibility of modulus stabiliza…
