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…

Seiberg-Witten Map with Lorentz-Invariance and Gauge-Covariant Star Product

M. Chaichian, M. N. Mnatsakanova, M. Oksanen

We develop the Seiberg-Witten map using the gauge-covariant star product with the noncommutativity tensor . The latter guarantees the Lorentz invariance of the theory. T…

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…

Can the gamma-ray bursts travelling through the interstellar space be explained without invoking the drastic assumption of Lorentz invariance violation?

Masud Chaichian, Iver Brevik, Markku Oksanen

Experimental observations indicate that gamma-ray bursts (GRB) and high-energy neutrino bursts may travel at different speeds with a typical delay measured at the order of hours or…

Dispersion of Light Traveling through the Interstellar Space, Induced and Intrinsic Lorentz Invariance Violation

Iver Brevik, Masud Chaichian, Markku Oksanen

Theoretical models and experimental observations suggest that gamma-ray bursts (GRB) and high-energy neutrino bursts travelling through the interstellar space may reach the Earth a…

Sakharov's induced gravity and the Poincaré gauge theory

Masud Chaichian, Markku Oksanen, Anca Tureanu

We explore Sakharov's seminal idea that gravitational dynamics is induced by the quantum corrections from the matter sector. This was the starting point of the view that gravity ha…
