Can the gamma-ray bursts travelling through the interstellar space be explained without invoking the drastic assumption of Lorentz invariance violation?
Chaichian, Masud; Brevik, Iver Håkon; Oksanen, Markku (Peer reviewed; Journal article, 2021)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 days. We discuss two potential interpretations ... -
Dispersion of light traveling through the interstellar space, induced and intrinsic Lorentz invariance violation
Brevik, Iver Håkon; Chaichian, Masud; Oksanen, Markku (Peer reviewed; Journal article, 2021)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 at different speeds. We propose and study ... -
Electric current and heat production by a neutral carrier: An effect of the axion
Brevik, Iver Håkon; Chaichian, Masud (Peer reviewed; Journal article, 2022)A general axion-electrodynamic formalism is presented on the phenomenological level when the environment is dielectric (permittivity and permeability assumed to be constants). Thereafter, a strong and uniform magnetic field ... -
Remarks on the Abraham-Minkowski problem, from the formal and from the experimental side
Brevik, Iver Håkon; Chaichian, Masud; Cotaescu, I. I. (Peer reviewed; Journal article, 2021)We analyze the Abraham–Minkowski problem known from classical electrodynamics from two different perspectives. First, we follow a formal approach, implying use of manifolds with curved space sections in accordance with ...
