Renormalizable and unitary nonlocal quantum field theory with CPT violation and its implication
Moshe M. Chaichian, Markku A. Oksanen, Anca Tureanu
It is a common belief that any relativistic nonlocal quantum field theory encounters either the problem of renormalizability or unitarity or both of them. It is also known that any…
Photon Propagation through Axion Clouds around Magnetized Compact Objects: Time Delays and Polarimetric Signatures
M. M. Chaichian, B. A. Couto e Silva, B. L. Sánchez-Vega
Temporal offsets between Gamma-Ray Bursts (GRBs) and high-energy neutrinos probe propagation effects in extreme astrophysical environments. We investigate whether such offsets can…
CPT Violation, Mirror World and Implications for Baryon Asymmetry
M. M. Chaichian, M. Gogberashvili, M. N. Mnatsakanova +1
We propose a novel model in which the Universe is created as a pair of coordinate-reversed counterparts, forming a globally CPT-symmetric system that permits local CPT violations w…
Rotation of the polarization plane in axion fields: application to neutron star polar cap regions
Iver H. Brevik, Moshe M. Chaichian, Tiberiu Harko +1
We study observable manifestations of an axion field, focusing on possible polarizational effects for electromagnetic wave propagating in such a special magnetoelectric medium. The…
Comment on the "Electric Power Generation from Earth's Rotation through its Own Magnetic Field"
Iver H. Brevik, Moshe M. Chaichian, Mikhail I. Katsnelson
The suggestion made by C. F. Chyba and K. P. Hand about electric power generation from Earth's rotation through its own magnetic field is intriguing [1, 2]. Due to the importance o…
Very Special Relativity: Cherenkov Effect and an Analogy with Minkowski's Electrodynamics of Continuous Media
I. H. Brevik, M. M. Chaichian, B. A. Couto e Silva +1
In this work, we explore the implications of the Cohen and Glashow Very Special Relativity (VSR) theory, a framework that introduces Lorentz invariance violation through the presen…
