摘要: A systematic expansion of the many-body master equation for active matter, in which motors power configurational changes as cytoskeleton, is shown to yield a description steady state and responses terms an effective temperature. The temperature depends on susceptibility Peclet number measures their strength relative thermal Brownian diffusion. analytic prediction agree with previous numerical simulations experiments. mapping also establishes aging matter that kinetically jammed.
