Active Self-Consistent Field Theory for Ornstein-Uhlenbeck PolymersNew

This paper develops an active self-consistent field theory (ASCFT) for studying the steady-state behavior of active Ornstein-Uhlenbeck polymers. Starting from stochastic equations of motion under the unified colored noise approximation, the authors derive an effective Hamiltonian that extends classical polymer field theory to non-equilibrium systems. The resulting free energy functional incorporates the Flory-Huggins interaction parameter χN, providing a framework for analyzing phase behavior and structural properties of active polymer solutions.
