Supersymmetry in Stochastic Processes with Higher-Order Time Derivatives

arXiv:quant-ph/9705042 · doi:10.1016/S0375-9601(97)00660-9

Abstract

A supersymmetric path integral representation is developed for stochastic processes whose Langevin equation contains any number N of time derivatives, thus generalizing the Langevin equation with inertia studied by Kramers, where N=2. The supersymmetric action contains N fermion fields with first-order time derivatives whose path integral is evaluated for fermionless asymptotic states.
