Probing the early universe with a generalized action
Ranajit Mandal, Dalia Saha, Mohosin Alam +1
Possibly, the most general action in the background of isotropic and homogeneous space-time has been considered to study the quantum evolution of the early universe, apart from a c…
Early Universe with modified scalar-tensor theory of gravity
Ranajit Mandal, Chandramouli Sarkar, Abhik Kumar Sanyal
Scalar-tensor theory of gravity with non-minimal coupling is a fairly good candidate for dark energy, required to explain late-time cosmic evolution. Here we study the very early s…
Resolving the issue of branched Hamiltonian in modified Lanczos-Lovelock gravity
Soumendranath Ruz, Ranajit Mandal, Subhra Debnath +1
The Hamiltonian constraint Hc = NH = 0, defines a diffeomorphic structure on spatial manifolds by the lapse function N in general theory of relativity. However, it is not manifest…
Scalar tensor theory of gravity carrying a conserved current
Abhik Kumar Sanyal
A general scalar-tensor theory of gravity carries a conserved current for a trace free minimally coupled scalar field, under the condition that the potential of the nonminim…
Hamiltonian formulation of curvature squared action
Abhik Kumar Sanyal
It has been observed earlier that, in principle, it is possible to obtain a quantum mechanical interpretation of higher order quantum cosmological models in the spatially homogeneo…
