摘要
The Lorentz violating term in the photon sector of Standard Model Extension, L-K = -1/4(k(F))alpha beta mu nu(FF mu nu)-F-alpha beta (here referred to as the Kostelecky term), breaks conformal invariance of electromagnetism and enables a superadiabatic amplification of magnetic vacuum fluctuations during inflation. For a wide range of values of parameters defining Lorentz symmetry violation and inflation, the present-day magnetic field can have an intensity of order of nanogauss on megaparsec scales and then Could explain the large-scale magnetization of the universe.
