Early universe in view of a modified theory of gravity

Ranajit Mandal, Dalia Saha, Mohosin Alam +1

We study the quantum evolution of the early universe, its semi-classical analogue together with inflationary regime, in view of a generalized modified theory of gravity. The action…

Canonical equivalence in anisotropic models for higher order theory of gravity

Subhra Debnath, Abhik Kumar Sanyal

We show that as in the case of isotropic models, the `Dirac Algorithm' and `Modified Horowitz' Formalism' lead to identical phase-space structure of the Hamiltonian for the gravita…

Canonical formulation of Pais-Ulhenbeck action and resolving the issue of branched Hamiltonian

Kaushik Sarkar, Nayem Sk, Ranajit Mandal +1

Shortcomings of Dirac's constrained analysis in the context of fourth order Pais-Uhlenbeck oscillator action and the appearance of badly affected phase-space Hamiltonian for a gene…

Partition function of massless scalar field in Schwarzschild background

Abhik Kumar Sanyal

Using thermal value of zeta function instead of zero temperature, the partition function of quantized fields in arbitrary stationary backgrounds was found to be independent of unde…

Canonical formulation of scalar curvature squared action in higher dimensions

Subhra Debnath, Soumendranath Ruz, Abhik Kumar Sanyal

Canonical formulation for an action containing scalar curvature squared term in arbitrary dimension has been performed in maximally symmetric space-time. The quantum dynami…
