Tidal Love Numbers of Black Holes and Neutron Stars in the Presence of Higher Dimensions: Implications of GW170817
Kabir Chakravarti, Sumanta Chakraborty, Sukanta Bose +1
We calculate the tidal Love numbers of black holes and neutron stars in the presence of higher dimensions. The perturbation equations around an arbitrary static and spherically sym…
Fate of Strong Cosmic Censorship Conjecture in Presence of Higher Spacetime Dimensions
Mostafizur Rahman, Sumanta Chakraborty, Soumitra SenGupta +1
Strong cosmic censorship conjecture has been one of the most important leap of faith in the context of general relativity, providing assurance in the deterministic nature of the as…
Hilltop inflation and generation of helical magnetic field
Sumanta Chakraborty, Supratik Pal, Soumitra SenGupta
Primordial magnetic field generated in the inflationary era can act as a viable source for the present day intergalactic magnetic field of sufficient strength. We present a fundame…
On some novel features of the Kerr-Newman-NUT Spacetime
Sajal Mukherjee, Sumanta Chakraborty, Naresh Dadhich
In this work we have presented a special class of Kerr-Newman-NUT black hole, having its horizon located precisely at , for , where , , and a…
Radion induced inflation on non-flat brane and modulus stabilization
Indrani Banerjee, Sumanta Chakraborty, Soumitra SenGupta
Warped braneworld models has the potential to provide a plausible resolution to the gauge hierarchy problem but at the cost of introduction of an additional field, namely the inter…
Null boundary terms for Lanczos-Lovelock gravity
Sumanta Chakraborty, Krishnamohan Parattu
We derive boundary terms appropriate for the general Lanczos-Lovelock action on a null boundary, when Dirichlet boundary conditions are imposed. We believe that these boundary term…
Noether Current, Black Hole Entropy and Spacetime Torsion
Sumanta Chakraborty, Ramit Dey
We show that the presence of spacetime torsion, unlike any other non-trivial modifications of the Einstein gravity, does \emph{not} affect black hole entropy. The theory being diff…
Inflation driven by Einstein-Gauss-Bonnet gravity
Sumanta Chakraborty, Tanmoy Paul, Soumitra SenGupta
We have explicitly demonstrated that scalar coupled Gauss-Bonnet gravity in four dimension can have non-trivial effects on the early inflationary stage of our universe. In particul…
Late-time acceleration driven by shift-symmetric Galileon in the presence of Torsion
Rabin Banerjee, Sumanta Chakraborty, Pradip Mukherjee
A shift-symmetric Galileon model in presence of spacetime torsion has been constructed for the first time. This has been realized by localizing (or, gauging) the Galileon symmetry…
