Active Model B${}^{-}$ from Mass-Conserving Reaction-Diffusion Systems

Davide Toffenetti, Beatrice Nettuno, Henrik Weyer +1

We show that the late-time dynamics of a minimal three-component mass-conserving reaction--diffusion system reduce to a scalar active field theory, Active Model B${}^{-}$ (AMB${}^{-}$), in…
