The difference in the number of left and right-handed modes in this man's operator equals the topological charge in QCD according to the Atiyah-Singer index theorem.
The difference in the number of left and right-handed modes in this man's operator equals the topological charge in QCD according to the Atiyah-Singer index theorem. A left-handed and a right-handed object named for Weyl can be combined to form a four component object named for this physicist.  Fermions which are not their own antiparticles are named for this physicist and contrast with (*) Majorana fermions. A distribution named for this guy is the derivative of the Heaviside step function. He used a set of anticommuting matrices to factor the Klein-Gordon equation in order to derive a first-order Lorentz invariant equation for spin half particles.  For 10 points, name this English physicist whose equation predicted the existence of antimatter.
