Exact Active Dynamics
Even though there has been substantial progress in the field of active matter, there is a lack of exact analytic calculations to understand the dynamics of active particles. We developed a direct method, rooted in the polymer statistics [Hermans and Ullman, Physica 18, 951 (1952)] and the Fokker-Planck equation, to compute dynamical moments exactly.
