A second order constitutive theory for polyatomic gases: theory and applications
Anirudh Singh Rana, Sukratu Barve
In the classical irreversible thermodynamics (CIT) framework, the Navier Stokes Fourier (NSF) constitutive equations are obtained so as they satisfy the entropy inequality, by and…
Importance of initial conditions in the polarization of complex networks
Snehal M. Shekatkar, Sukratu Barve
Currently used models of opinion formation use random initial conditions. In reality, most people in a social network, except for a small fraction of the population, are initially…
Noise Kernel for Self-similar Tolman Bondi Metric: Fluctuations on Cauchy Horizon
Seema Satin, Kinjalk Lochan, Sukratu Barve
We attempt to calculate the point separated Noise Kernel for self similar Tolman Bondi metric, using a method similar to that developed by Eftekharzadeh et. al for ultra-static spa…
Depletion of energy from Naked Singular regions during gravitational collapse
S. Jhingan, I. H. Dwivedi, S. Barve
A distinguishable and observable physical property of Naked Singular Regions of the spacetime formed during a gravitational collapse has important implications for both experimenta…
Conformal transformations near Naked Singularities - I
Sukratu Barve
We show that the behaviour of the outgoing radial null geodesic congruence on the boundary of the trapped region (suitably defined as a four dimensional region) is related to the p…
Reissner Nordström Background Metric in Dynamical Co-ordinates: Exceptional Behaviour of Hadamard States
Sukratu Barve, A. R. Prasanna
We cast the Reissner Nordstrom solution in a particular co-ordinate system which shows dynamical evolution from initial data. The initial data for the case is regular. This p…
A Connection of Apparent Horizon and Naked Singularities in Spherical Dust Collapse
Sukratu Barve
We show that the behaviour of outgoing radial null geodesic congruence on the apparent horizon is related to the property of nakedness in spherical dust collapse justifying the dif…
Divergence of the Quantum Stress Tensor on the Cauchy Horizon in 2-d Dust Collapse
Sukratu Barve, T. P. Singh, Cenalo Vaz
We prove that the quantum stress tensor for a massless scalar field in two dimensional non-selfsimilar Tolman Bondi dust collapse and Vaidya radiation collapse models diverges on t…
Spherical gravitational collapse: tangential pressure and related equations of state
Sukratu Barve, T. P. Singh, Louis Witten
We derive an equation for the acceleration of a fluid element in the spherical gravitational collapse of a bounded compact object made up of an imperfect fluid. We show that non-si…
A simple derivation of the naked singularity in spherical dust collapse
Sukratu Barve, T. P. Singh, Cenalo Vaz +1
We describe a simple method of determining whether the singularity that forms in the spherically symmetric collapse of inhomogeneous dust is naked or covered. This derivation consi…
The Quantum Stress-Tensor in Self-Similar Spherical Dust Collapse
Sukratu Barve, T. P. Singh, Cenalo Vaz +1
We calculate the quantum stress tensor for a massless scalar field in the 2-d self-similar spherical dust collapse model which admits a naked singularity. We find that the outgoing…
Particle Creation in the Marginally Bound, Self Similar Collapse of Inhomogeneous Dust
S. Barve, T. P. Singh, Cenalo Vaz +1
We consider the evaporation of the (shell focusing) naked singularity formed during the self-similar collapse of a marginally bound inhomogeneous dust cloud, in the geometric optic…
Naked singularities and the Weyl Curvature Hypothesis
Sukratu Barve, T. P. Singh
We examine the growth of the Weyl curvature in two examples of naked singularity formation in spherical gravitational collapse - dust and the Vaidya spacetime. We find that the Wey…
Are naked singularites forbidden by the second law of thermodynamics?
Sukratu Barve, T. P. Singh
By now, many examples of naked singularities in classical general relativity are known. It may however be that a physical principle over and above the general theory prevents the o…
