Dynamical Chiral Symmetry Breaking in QED in a Magnetic Field: Toward Exact Results
arXiv:hep-th/9811079 · doi:10.1103/PhysRevLett.83.1291
Abstract
We describe a (first, to the best of our knowledge) essentially soluble example of dynamical symmetry breaking phenomenon in a 3+1 dimensional gauge theory without fundamental scalar fields: QED in a constant magnetic field.
