Emergent flocking dynamics in chemorepulsive active colloids: interplay of disorder and noise
Sagarika Adhikary, Rajesh Singh
Recent studies of active colloidal matter have revealed that a global polar order can arise from chemorepulsive interactions among particles without any explicit alignment interact…
Flocking transition in phoretically interacting active particles with pinning disorder
Sagarika Adhikary, Arvin Gopal Subramaniam, Rajesh Singh
Recent studies in the collective behavior of active colloids have shown that a global polar order may emerge due to long-ranged chemo-repulsive interactions between them. Here, we…
Minimal mechanism for flocking in phoretically interacting active particles
Arvin Gopal Subramaniam, Sagarika Adhikary, Rajesh Singh
Coherent collective motion is a widely observed phenomenon in active matter systems. Here, we report a flocking transition mechanism in a system of chemically interacting active co…
Pattern formation and spatiotemporal chaos in relativistic degenerate plasmas
S. Das Adhikary, A. P. Misra
We numerically study the nonlinear interactions of high-frequency circularly polarized electromagnetic (EM) waves and low-frequency electron-acoustic (EA) density perturbations dri…
