Exact Solutions and Constraints on the Dark Energy Model in FRW Universe

Albin Joseph, Rajib Saha

The inflationary epoch and the late time acceleration of the expansion rate of universe can be explained by assuming a gravitationally coupled scalar field. In this article, we pro…

Hamiltonian Formalism for Nonlocal Gravity Models

Pawan Joshi, Utkarsh Kumar, Sukanta Panda

Nonlocal gravity models are constructed to explain the current acceleration of the universe. These models are inspired by the infrared correction appearing in Einstein Hilbert acti…

Higher Derivative Theory For Curvature Term Coupling With Scalar Field

pawan Joshi, Sukanta Panda

Higher order derivative theories, generally suffer from instabilities, known as Ostrogradsky instabilities. This issue can be resolved by removing any existing degeneracy present i…

Blackhole in Nonlocal Gravity: Comparing Metric from Newmann-Janis Algorithm with Slowly Rotating Solution

Utkarsh Kumar, Sukanta Panda, Avani Patel

The strong gravitational field near massive blackhole is an interesting regime to test General Relativity(GR) and modified gravity theories. The knowledge of spacetime metric aroun…

Quantum aspects of antisymmetric tensor field with spontaneous Lorentz violation

Sandeep Aashish, Sukanta Panda

We study the quantization of a simple model of antisymmetric tensor field with spontaneous Lorentz violation in curved spacetime. We evaluate the 1-loop corrections at first order…

Avoiding instabilities in antisymmetric tensor field driven inflation

Sandeep Aashish, Abhilash Padhy, Sukanta Panda

Models of inflation with antisymmetric tensor studied in the past are plagued with ghost instability even in an unperturbed FRW background. We show that it is possible to avoid gho…
