Rate My Professor Marek Krasnansky

Dr. Marek Krasnansky serves as Associate Professor of Physics in the Department of Chemistry and Physics, College of Natural Sciences and Mathematics, at West Virginia State University, a position he has held since 2007. He obtained his Mgr. degree from Comenius University in Bratislava, Slovakia, and earned his Ph.D. in Physics from the University of Connecticut in January 2007. His dissertation, "Quantum gauge field theory," addressed canonical quantization of gauge theories in the spatial axial gauge, restoring rotational symmetry for nonabelian theories with gauge fixing A_3^a = 0, and similarities to gauge invariant quantities in the Weyl gauge. It further developed integration-by-parts rules for Feynman diagrams with massive scalar propagators in background electromagnetic fields, providing a diagrammatic interpretation of mass renormalization in the two-loop scalar QED Heisenberg-Euler effective action. For constant backgrounds, the fully renormalized effective action was derived without evaluating integrals or specifying propagators. Special cases like self-dual fields reduced the two-loop action to one-loop quantities using recursion relations, applicable in arbitrary even dimensions.
