Relic of the Kink Shape Mode in a Topological Thick Brane - some implications
Gahan Chattopadhyay, Soumitra Sengupta
The kink soliton provides a simple construction of a topological thick 3-brane sourced by a minimally coupled canonical scalar field in five-dimensional general relativity. Althoug…
Kaluza-Klein Gravitons in a Higher Curvature Warped Geometry : A New Perspective
Abhirup Karmakar, Isika Mandal, Soumitra SenGupta
Kaluza-Klein (KK) Gravitons are the direct collider imprints of the higher dimensional bulk physics in our four dimensional universe, arising from the compactification of an extra…
Tachyonic (In)stability in Randall-Sundrum Braneworld Scenarios
Abhirup Karmakar, Soumitra SenGupta
Low-energy effective theories provide a natural description of four-dimensional physics in higher-dimensional geometries, where the imprint of the bulk geometry appears as paramete…
Phase space analysis of cosmologies: revisiting attractor-to-GR
Gahan Chattopadhyay, Soumitra Sengupta
Phase space analysis of -Gravity, a simple generalization of Einstein's General theory of Relativity has been of interest especially in the context of Cosmology. Beyond its s…
Bouncing Cosmologies in modified gravity with space time torsion
Sonej Alam, Somasri Sen, Soumitra Sengupta
We explore the possibility of realizing a non-singular bounce in the early universe within the framework of modified gravity with spacetime torsion. In Einstein Cartan theory, tors…
Thermal description of braneworld effective theories
Soham Bhattacharyya, Soumitra SenGupta
Low-energy effective theories provide the natural description of four-dimensional physics in higher-dimensional geometries, where the imprint of the bulk appears as parameters of t…
Can spacetime torsion source an extremely red-tilted cosmological GW background?
Arko Bhaumik, Bhaswati Mandal, Soumitra SenGupta
In the presence of spacetime torsion, any generic model of gravity is conformally dual to a scalar-tensor theory augmented with a second rank antisymmetric massless degree o…
Analyzing the general conditions for modulus stabilization in a warped braneworld
Soham Bhattacharyya, Soumitra SenGupta
In braneworld scenarios with compact extra dimensions, the modulus field typically remains undetermined without an appropriate stabilization mechanism. A common approach introduces…
Moduli Dynamics in Effective Nested Warped Geometry in Four Dimensions and Some Cosmological Implications
Arko Bhaumik, Soumitra SenGupta
We analyze the effective four-dimensional dynamics of the extra-dimensional moduli fields in curved braneworlds having nested warping, with particular emphasis on the doubly warped…
Absence of antisymmetric tensor fields : Clue from f(R) model of gravity
Sonej Alam, Somasri Sen, Soumitra Sengupta
One of the surprising aspects of the present Universe, is the absence of any noticeable observable effects of higher-rank antisymmetric tensor fields in any natural phenomena. Here…
