When two active Brownian particles collide, they slide along each other until they can
continue their free motion. For persistence lengths much larger than the particle diameter …

We consider two species of self-propelled point particles: A-particles and B-particles. The
orientations between nearby particles are subject to pair interactions of different strength for …

We highlight the importance of long-range correlations in active matter systems of dilute self-
propelling particles even in the absence of global order by demonstrating that long-range …
