題目：Field-embedded particles driven by active flips

要旨：Systems of independent active particles embedded into a fluctuating environment are relevant to many areas of soft-matter science. We use a minimal model of noninteracting spin-carrying Brownian particles in a Gaussian field and show that activity-driven spin dynamics leads to patterned order. We find that the competition between mediated interactions and active noise alone can yield such diverse behaviors as phase transitions and microphase separation, from lamellar up to hexagonal ordering of clusters. These rest on complex multibody interactions. Our approach combines Monte-Carlo simulations with analytical methods based on dynamical density functional approaches.
