Doi-Peliti Field Theory of free Active Ornstein-Uhlenbeck Particles
ORAL
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 diagonalise 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.
