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…
