A linear response relation in general relativity with applications to dense matter relativistic stars
Seema Satin
A new formalism in general relativity with a linear response relation between perturbed Einstein tensor and the stress-energy tensor is presented. Basic concepts are borrowed from…
The hydrodynamic approximation of the semiclassical dissipation kernel in stochastic gravity
Seema Satin
Semiclassical stochastic gravity is aimed at studying extended structure formation in the early universe. Rigorous developments in this area include the semiclassical noise and dis…
Induced polar perturbations in relativistic stars with stochastic effects in the dense matter at sub-hydro mesoscopic scales: A theoretical probe at intermediate length scales
Seema Satin
A linear response relation between metric and fluid perturbations driven by a background noise source is used as a framework for obtaining non-radial polar perturbations in dense m…
Formalism for stochastic perturbations and analysis in relativistic stars
Seema Satin
Perturbed Einstein's equations with a linear response relation and a stochastic source, applicable to a relativistic star model are worked out . These perturbations which are stoch…
Correspondences between scalar field and fluid fluctuations in curved spacetime
Seema Satin
A correspondence between scalar field fluctuations and generalized fluctuations in a hydrodynamic approximation of fields is obtained. The results presented here are of interest to…
A Linear Response relation for perturbations in compact stars and the classical Einstein-Langevin formalism
Seema Satin
We give a linear response relation for perturbations in relativistic stars and classify them in terms of implicit and induced perturbations. The focus in this article is on the ind…
