Algebraic spinors and directed random walks in the McKane-Parisi-Sourlas theorem

  • 28 Accesses


We present the Dirac propagator as a random walk on anS D−1 sphere for Majorana spinors, even spinor space, Dirac spinors, and Chevalley-Crumeyrolle spinors built from Minkowski space. We propose the Dirac propagator constructed from Chevalley-Crumeyrolle spinors as the generators of a Markov process such that McKane-Parisi-Sourlas theorem can be applied to calculate the expectation values for functions of local times.
