Magnetogenesis in Matter - Ekpyrotic Bouncing Cosmology
Ratna Koley, Sidhartha Samtani
In the recent past there have been many attempts to associate the generation of primordial magnetic seed fields with the inflationary era, but with limited success. We thus take a…
Scalar Kaluza-Klein modes in a multiply warped braneworld
Ratna Koley, Joydip Mitra, Soumitra SenGupta
The Kaluza-Klein (KK) modes of a massive scalar field on a 3-brane embedded in six dimensional multiply warped spacetime are determined. Due to the presence of warping along both t…
A critical analysis of thermodynamic properties of braneworld black holes in anti-de Sitter spacetime
Ratna Koley, Joydip Mitra, Supratik Pal +1
Thermodynamic properties of Schwarzschild-Anti de-Sitter (Sch-AdS) and Reissner-Nordström-Anti de-Sitter (RN-AdS) blackholes in 3+1 dimensional spacetime are studied critically wit…
Localization of fields on brane
Ratna Koley
Warped braneworld scenario provides an alternative to the usual Kaluza-Klein compactification of extra dimensions through the so-called localization of fields. Randall-Sundrum type…
Modulus stabilization of generalized Randall Sundrum model with bulk scalar field
Ratna Koley, Joydip Mitra, Soumitra SenGupta
We study the stabilization of inter-brane spacing modulus of generalized warped brane models with a nonzero brane cosmological constant. Employing Goldberger-Wise stabilization pre…
Fermion localization in generalised Randall Sundrum model
Ratna Koley, Joydip Mitra, Soumitra SenGupta
A generalized two-brane Randall-Sundrum warped braneworld model admits of solutions of the warp factor for both positive or negative cosmological constant on the visible 3-brane wh…
