Understanding quorum sensing self-organization: Clustering and defect-induced ordering of diffusing particles
Feifei Liu, Vyacheslav R. Misko, Yunyun Li +1
Quorum sensing (QS) is known in biology as a form of intercellular communication mediated by signaling molecules called autoinducers. The QS protocol governs the transition from in…
Large-scale dynamics in visual quorum sensing chiral suspensions
Yuxin Zhou, Qingqing Yin, Shubhadip Nayak +4
Motility induced phase separation is an efficient aggregation mechanism of active matter, yet biological systems exhibit richer organization through communication among constituent…
Active Particle Diffusion in Convection Roll Arrays
Pulak Kumar Ghosh, Fabio Marchesoni, Yunyun Li +1
We numerically investigated the Brownian motion of active Janus particles in a linear array of planar counter-rotating convection rolls at high Péclet numbers. Similarly to passiv…
Binary Mixtures in Linear Convection Arrays
Pulak Kumar Ghosh, Yuxin Zhou, Yunyun Li +2
We numerically investigated the dynamics of a mixture of finite-size active and passive particles in a linear array of convection rolls. The interplay of advection and steric inter…
Diffusion Transients in Motility-Induced Phase Separation
Shubhadip Nayak, Poulami Bag, Pulak K. Ghosh +4
We numerically investigate normal diffusion in a two-dimensional athermal suspension of active particles undergoing motility-induced phase separation. The particles are modeled as…
