Spontaneous Magnetization in Lorentz Invariant Theories
arXiv:hep-th/9505113 · doi:10.1016/0370-2693(95)00669-C
Abstract
In a class of three-dimensional Abelian gauge theories with both light and heavy fermions, heavy chiral fermions can trigger dynamical generation of a magnetic field, leading to the spontaneous breaking of the Lorentz invaiance. Finite masses of light fermions tend to restore the Lorentz invariance.
