We study a robust model of self-propelled rods interacting via volume exclusion and show that its collective dynamics encompasses both that of the corresponding Vicsek-style model (where local alignment is the sole interaction), and motility-induced phase separation (which occurs when repulsion is dominant). These results unify these heretofore largely disconnected bodies of knowledge on dry active matter and clarify the nature of the various phases involved.

  1. The Interplay of Polar and Nematic Order in Active Matter: Implications for Non-Equilibrium Physics and Biology

    cond-mat.soft 2025-06 conditional novelty 2.0 of 10

    A review argues that polar and nematic order frequently coexist in active biological matter, so unified mixed-symmetry models are needed to describe it.
