Inferring activity from fluid flow in continuum models of active matter
Aditya Mohapatra, Sagarika Adhikary, Rajesh Singh
Active matter systems are driven out of thermodynamic equilibrium by localized, microscale energy dissipation. While hydrodynamic continuum frameworks are highly successful at simu…
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…
Collective dynamics and phase transition of active matter in presence of orientation adapters
Sagarika Adhikary, S. B. Santra
In this work, the orientation adapter, a species of active particles that adapt their direction of motion from the other active particles, is introduced. The orientation adapters e…
Pattern formation and phase transition in the collective dynamics of a binary mixture of polar self-propelled particles
Sagarika Adhikary, S. B. Santra
The collective behavior of a binary mixture of polar self-propelled particles (SPPs) with different motile properties is studied. The binary mixture consists of slow-moving SPPs (s…
