Alternative approach to the Starobinsky model for inflation scenarios
Masud Chaichian, Amir Ghal'e, Markku Oksanen
The model of gravity with the corresponding shallow potential in the Einstein frame is consistent with the observations. Recently, many efforts have been made to generalize…
Mimetic Tensor-Vector-Scalar Cosmology: Incorporating Dark Matter, Dark Energy and Stiff Matter
David Benisty, Masud Chaichian, Markku Oksanen
Phenomenological implications of the Mimetic Tensor-Vector-Scalar theory (MiTeVeS) are studied. The theory is an extension of the vector field model of mimetic dark matter, where a…
Non-Projectable Horava-Lifshitz Gravity without Unwanted Scalar Graviton
Masud Chaichian, Josef Kluson, Markku Oksanen
We consider a way of eliminating the unwanted scalar graviton from Horava-Lifshitz gravity. That is achieved via introduction of certain additional constraints. We perform canonica…
Higher derivative gravity with spontaneous symmetry breaking: Hamiltonian analysis of new covariant renormalizable gravity
Masud Chaichian, Josef Klusoň, Markku Oksanen +1
In order to explore some general features of modified theories of gravity which involve higher derivatives and spontaneous Lorentz and/or diffeomorphism symmetry breaking, we study…
Arnowitt-Deser-Misner representation and Hamiltonian analysis of covariant renormalizable gravity
Masud Chaichian, Markku Oksanen, Anca Tureanu
We study the recently proposed Covariant Renormalizable Gravity (CRG), which aims to provide a generally covariant ultraviolet completion of general relativity. We obtain a space-t…
