John M. CornwallJohn M. Cornwall's main research interest is non-perturbative quantum chromodynamics, both in four dimensions and in three (with applications to the functional Schrödinger equation and to high temperatures). Many of these results depend heavily on th pinch technique, as described in The Pinch Technique and its Applications to Non-Abelian Gauge Theories. He has also worked fairly recently on the applications of non-Abelian gauge theories to the early universe, in primordial magnetic fields and baryon asymmetry. Earlier work was in dynamical symmetry breaking, the equivalence theorem and effective potentials for gauge theories. He has also worked in space physics, including the aurora and Earth's ring current. Read More Read Less
