John B KogutJohn Benjamin Kogut, PhD, is an American theoretical physicist, specializing in high energy physics. He has contributed to the quark-parton model, light-cone quantization, quark confinement, lattice gauge theory, Quantum Chromodynamics (the field thery of quarks and gluons) in extreme environments (high temperatures and densities), and supercomputer simulations as a tool for theoretical physics. For 27 years Dr. Kogut was on the physics faculty of the Loomis Laboratory at the University of Illinois, Urbana-Champaign, retiring in 2005 as professor emeritus. Read More Read Less
