Catalysis of Dynamical Symmetry Breaking by a Magnetic Field
... At present there are only a few firmly established non-perturbative phenomena in 2+ 1 and, especially, 3+ 1 dimensional field theories. In this talk, I will describe one more such phenomenon: dynamical chiral symmetry breaking by a magnetic field. The talk is based on a series of the recent papers w ...
