Canonical equivalence, quantization and anisotropic inflation in higher order theory of gravity
Subhra Debnath, Abhik Kumar Sanyal
We construct phase-space structure of a typical higher-order theory of gravity, in the background of anisotropic Bianchi-1 mini-superspace, following `Modified Horowitz Formalism'…
Thermodynamics of irreversible particle creation phenomena and its cosmological consequence
Abhik Kumar Sanyal, Subhra Debnath
The study of particle creation phenomena at the expense of the gravitational field is of great research interest. It might solve the cosmological puzzle single-handedly, without th…
History of cosmic evolution with modified Gauss-Bonnet-dilatonic coupled term
Subhra Debnath, Soumendra Nath Ruz, Ranajit Mandal +1
Gauss-Bonnet-dilatonic coupling in four dimension plays an important role to explain late time cosmic evolution. However, this term is an outcome of low energy string effective act…
Euclidean wormholes with minimally coupled scalar fields
Soumendranath Ruz, Subhra Debnath, Abhik Kumar Sanyal +1
A detailed study of quantum and semiclassical Euclidean wormholes for Einstein's theory with a minimally coupled scalar field has been performed for a class of potentials. Massless…
Canonical formulation of curvature squared action in the presence of lapse function
Abhik Kumar Sanyal, Subhra Debnath, Soumendranath Ruz
Lapse function appears as Lagrange multiplier in Einstein-Hilbert action and its variation leads to the (0 0) equation of Einstein, which corresponds to the Hamiltonian constraint…
