Universalization as a physical guiding principle
Naresh Dadhich
In this essay, I wish to share a novel perspective based on the principle of universalization in arriving at the relativistic and quantum world from the classical world. I also del…
The critical role of shear in gravitational collapse
Pankaj S. Joshi, Rituparno Goswami, Naresh Dadhich
We investigate here how the shearing effects present within a collapsing matter cloud influence the outcome of gravitational collapse in terms of formation of either a black hole o…
Embedding Diagrams for the Reissner-Nordström spacetime
Aseem Paranjape, Naresh Dadhich
We consider embedding diagrams for the Reissner-Nordström spacetime. We embed the and planes into 3-Minkowski/Euclidean space and discuss the relation between the d…
The role of the equation of state and the space-time dimension in spherical collapse
Naresh Dadhich, S. G. Ghosh, D. W. Deshkar
We study the spherically symmetric collapse of a fluid with non-vanishing radial pressure in higher dimensional space-time. We obtain the general exact solution in the closed form…
Action based approach to the dynamics of extended bodies in General Relativity
Jeeva Anandan, Naresh Dadhich, Parampreet Singh
We present, for the first time, an action principle that gives the equations of motion of an extended body possessing multipole moments in an external gravitational field, in the w…
Scalar and Spinor Perturbation to the Kerr-NUT Spacetime
Banibrata Mukhopadhyay, Naresh Dadhich
We study the scalar and spinor perturbation, namely the Klein-Gordan and Dirac equations, in the Kerr-NUT space-time. The metric is invariant under the duality transformation invol…
