Solutions on a brane in a bulk spacetime with Kalb-Ramond field
Sumanta Chakraborty, Soumitra SenGupta
Effective gravitational field equations on a brane have been derived, when the bulk spacetime is endowed with the second rank antisymmetric Kalb-Ramond field. Since both the gravit…
Spherically symmetric brane spacetime with bulk gravity
Sumanta Chakraborty, Soumitra SenGupta
Introducing term in the five-dimensional bulk action we derive effective Einstein's equation on the brane using Gauss-Codazzi equation. This effective equation is…
Geometrical variables with direct thermodynamic significance in Lanczos-Lovelock gravity
Sumanta Chakraborty, T. Padmanabhan
It has been shown in an earlier work [arXiv:1303.1535] that there exists a pair of canonically conjugate variables in general relativity which also act as therm…
Evolution of Spacetime arises due to the departure from Holographic Equipartition in all Lanczos-Lovelock Theories of Gravity
Sumanta Chakraborty, T. Padmanabhan
In the case of general relativity one can interpret the Noether charge in any bulk region as the heat content of its boundary surface. Further, the time evolution of spacetime…
Equilibrium configuration of perfect fluid orbiting around black holes in some classes of alternative gravity theories
Sumanta Chakraborty
The hydrodynamic behaviour of perfect fluid orbiting around black holes in spherically symmetric spacetime for various alternative gravity theories has been investigated. For this…
Black hole kinematics: the "in"-vacuum energy density and flux for different observers
Suprit Singh, Sumanta Chakraborty
We have investigated the local invariant scalar observables - energy density and flux - which explicitly depend on the kinematics of the concerned observers in the Vaidya gravitati…
Higher curvature gravity at the LHC
Sumanta Chakraborty, Soumitra SenGupta
We investigate brane-world models in different viable gravity theories where the Lagrangian is an arbitrary function of the curvature scalar. Deriving the warped metric for…
Bulk scalar field in warped extra dimensional models
Sumanta Chakraborty, Soumitra SenGupta
This work presents a general formalism to analyze a generic bulk scalar field in a multiple warped extra-dimensional model with arbitrary number of extra dimensions. The Kaluza-Kle…
