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…
Shape-specific fluctuations of an active colloidal interface
Arvin Subramaniam, Tirthankar Banerjee, Rajesh Singh
Motivated by a recently synthesizable class of active interfaces formed by linked self--propelled colloids, we investigate the dynamics and fluctuations of a phoretically (chemical…
Scattering Angle Dependence of Fano Resonance Profiles in Cold Atomic Collisions Analyzed with the Complex Valued Parameter
Tanmay Singh, Raj Aryan Singh, Fumihiro Koike +2
The scattering angle dependence of Fano resonance profiles in cold atomic collisions has been theoretically studied. A complex-valued parameter with an analytical formula des…
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…
