Stationary equilibrium torus supported by Weyssenhoff ideal spin fluid in Schwarzschild spacetime -- I: Case of constant specific angular momentum distribution
Sayantani Lahiri, Claus Laemmerzahl
We consider a non-self-gravitating geometrically thick torus described by Weyssenhoff ideal spin fluid in a black hole spacetime. The Weyssenhof spin fluid shares the same symmetri…
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…
A note on spherically symmetric, static spacetimes in Kanno-Soda on-brane gravity
Sayan Kar, Sayantani Lahiri, Soumitra SenGupta
Spherically symmetric, static on-brane geometries in the Kanno-Soda (KS) effective scalar-tensor theory of on-brane gravity are discussed. In order to avoid brane collisions and/or…
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 $…
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…
