Segregation in Binary Mixture with Differential Contraction among Active Rings
Cell cortex contraction is vital for shaping cells, enabling movement, division, and responding to mechanical signals-processes crucial for multicellular organisms. Differential membrane contractions between cells significantly influence segregation. We present a model where active particle rings interact through differential contraction, showing that segregation arises from this mechanism, with ring activity functioning as an effective temperature. The interface decay exponent is close to λ∼1/3, differing from previous cluster fusion and diffusion model predictions.
