Density fluctuations of two-dimensional active-passive mixtures
文献摘要：
Dimension-dependent giant density fluctuations are a typical feature of active matter systems.In this work,we study the density fluctuation in two-dimensional mixtures of active and passive particles by Brownian dynamics simulations.The boundary of motility-induced phase separation is determined by the transition from unimodal to bimodal density distribution.A rapid increase of the fluctuation exponent near the boundary of phase separation in the plane of density and Peclet number was observed.When phase separation occurs,the fluctuation exponent is an approximate constant of 0.85.
