Ghost Free Theory in Unitary Gauge: A New Candidate
Pawan Joshi, Sukanta Panda, Archit Vidyarthi
We propose an algebraic analysis using a 3+1 decomposition to identify conditions for a clever cancellation of the higher derivatives, which plagued the theory with Ostrogradsky gh…
Hamiltonian Analysis of Nonlocal F(R) Gravity Models
Pawan Joshi, Sukanta Panda
We construct a Hamiltonian for the nonlocal F(R) theory in the present work. By this construction, we demonstrate the nature of the ghost degrees of freedom. Finally, we find condi…
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…
