Scalar Active Mixtures: The Nonreciprocal Cahn-Hilliard Model
October 2020
Continuum model of pattern formation due to nonreciprocal interaction between multiple species of scalar active matter
The classical Cahn-Hilliard model is minimally modified by supplementing the equilibrium Ginzburg-Landau dynamics with particle-number-conserving currents, which cannot be derived from a free energy, reflecting the microscopic departure from action-reaction symmetry.
