Dirac Born-Infeld inflation under constant roll conditions
Sayantani Lahiri
In the present paper, we aim to generalize the constant-roll inflation in the non-canonical set-up, particularly in the context of scalar Dirac-Born-Infeld (DBI) theory which has e…
Anisotopic inflation with a non-abelian gauge field in Gauss-Bonnet gravity
Sayantani Lahiri
In presence of Gauss-Bonnet corrections, we study anisotropic inflation aided by a massless gauge field where both the gauge field and the Gauss-Bonnet term are non-minimal…
Anisotropic inflation in Gauss-Bonnet gravity
Sayantani Lahiri
We study anisotropic inflation with Gauss-Bonnet correction in presence of a massless vector field. In this scenario, exact anisotropic power-law inflation is realized when the inf…
Black hole in a radially slant warped braneworld scenario
Sayantani Lahiri
As a follow-up to our previous paper arxiv: 1309.4244[hep-th], we determine radion induced spherically symmetric solution using the gradient approximation scheme, when two warped $…
Radion stability and induced, on-brane geometries in an effective scalar-tensor theory of gravity
Sayan Kar, Sayantani Lahiri, Soumitra SenGupta
About a decade ago, using a specific expansion scheme, effective, on-brane scalar tensor theories of gravity were proposed by Kanno and Soda (Phys.Rev. {\bf D 66} 083506 ,(2002)) i…
On the origin of brane cosmological constant in two-brane warped geometry model
Sayantani Lahiri, Soumitra SenGupta
In the backdrop of generalised Randall-Sundrum braneworld scenario, we look for the possible origin of an effective four dimensional cosmological constant () on the visibl…
