Figure 2: Motility-induced phase separation (MIPS) and kinetic temperature differences in coexisting phases at area fraction φ = 0.6. The particles are colored with respect to their kinetic temperature. (a,c) MIPS of overdamped active Brownian particles (ABPs) at Pe=200 and Pe=400, respectively. (b) MIPS of inertial ABPs at Pe=200 showing different kinetic temperatures in the dense and the dilute phase. (d) Inertia precludes MIPS at high activity (Pe=400).
