Title: Doi-Peliti field theory of free active ornstein-uhlenbeck particles
Authors: Bothe, M

Item Type: Journal Article
Abstract: We derive a Doi-Peliti field theory for free active Ornstein-Uhlenbeck particles, or, equivalently, free inertial Brownian particles, and present a way to diagonalize the quadratic part of the action and calculate the propagator. Unlike previous coarse-grained approaches this formulation correctly tracks particle identity and yet can easily be expanded to include potentials and arbitrary reactions.
