Universal scaling in active single-file dynamics.
@article{Dolai2020UniversalSI, title={Universal scaling in active single-file dynamics.}, author={Pritha Dolai and Arghya Das and Anupam Kundu and Chandan Dasgupta and Abhishek Dhar and K. Vijay Kumar}, journal={Soft matter}, year={2020} }
We study the single-file dynamics of three classes of active particles: run-and-tumble particles, active Brownian particles and active Ornstein-Uhlenbeck particles. At high activity values, the particles, interacting via purely repulsive and short-ranged forces, aggregate into several motile and dynamical clusters of comparable size, and do not display bulk phase-segregation. In this dynamical steady-state, we find that the cluster size distribution of these aggregates is a scaled function of…
