1. Fate of strong cosmic censorship conjecture in presence of higher spacetime dimensions / Rahman, Mostafizur ; Chakraborty, Sumanta ; SenGupta, Soumitra ; Sen, Anjan
Strong cosmic censorship conjecture has been one of the most important leap of faith in the context of general relativity, providing assurance in the deterministic nature of the associated field equations. [...]

2. Radion induced inflation on nonflat brane and modulus stabilization / Banerjee, Indrani ; Chakraborty, Sumanta ; SenGupta, Soumitra
Warped braneworld models have the potential to provide a plausible resolution to the gauge hierarchy problem but at the cost of introduction of an additional field, namely the interbrane separation or the radion field. [...]

3. Invisibility of antisymmetric tensor fields in the light of F(R) gravity / Das, Ashmita ; Paul, Tanmoy ; SenGupta, Soumitra
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 of gravity: why is our Universe is free of any perceptible signature of massless antisymmetric tensor modes? This work brings out a natural explanation of these phenomena through higher curvature quantum d.o.f. [...]

4. Radion tunneling in modified theories of gravity / Paul, Tanmoy ; SenGupta, Soumitra
We consider a five dimensional warped spacetime where the bulk geometry is governed by higher curvature F ( R ) gravity. [...]

5. Radion stabilization in higher curvature warped spacetime / Das, Ashmita ; Mukherjee, Hiya ; Paul, Tanmoy ; SenGupta, Soumitra

6. Fermion localization in higher curvature and scalar–tensor theories of gravity / Mitra, Joydip ; Paul, Tanmoy ; SenGupta, Soumitra
It is well known that, in a braneworld model, the localization of fermions on a lower dimensional submanifold (say a TeV 3-brane) is governed by the gravity in the bulk, which also determines the corresponding phenomenology on the brane. [...]

7. Bouncing cosmology from warped extra dimensional scenario / Das, Ashmita ; Maity, Debaprasad ; Paul, Tanmoy ; SenGupta, Soumitra
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. [...]

8. Gravity stabilizes itself / Chakraborty, Sumanta ; SenGupta, Soumitra
We show that a possible resolution to the stabilization of an extra spatial dimension (radion) can be obtained solely in the context of gravitational dynamics itself without the necessity of introducing any external stabilizing field. [...]
