Spontaneous demixing of chiral active mixtures in motility-induced phase separation

New Journal of Physics, 2023
The demixing and sorting strategies for chiral active mixtures are crucial to the biochemical and pharmaceutical industries. However, it remains uncertain whether chiral mixed particles can spontaneously demix without the aid of specific strategies.
