One of the most intriguing phenomena in active matter has been the gas–liquid-like motility-
induced phase separation (MIPS) observed in repulsive active particles. However,
experimentally, no particle can be a perfect sphere, and the asymmetric shape, mass
distribution, or catalysis coating can induce an active torque on the particle, which makes it a
chiral active particle. Here, using computer simulations and dynamic mean-field theory, we
demonstrate that the large enough torque of circle active Brownian particles in two …
