Collective dynamics of chemo-mechanical colloidal chains with active tips
Arvin Gopal Subramaniam, Rajesh Singh
We report a study of the emergent dynamics arising in two-dimensional suspensions of semi-flexible chains whose tip is chemically active, generating a phoretic field. By varying th…
Mechanics and statistics of a solvable model of an autophoretic colloidal chain
Arvin Gopal Subramaniam, Rajesh Singh
Equilibrium statistical mechanics owes much of its analytical tractability to symmetry: detailed balance, gradient flows, and the resulting vanishing of steady-state entropy produc…
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…
Intracellular phagosome shell is rigid enough to transfer outside torque to the inner spherical particle
Srestha Roy, Arvin Gopal Subramaniam, Snigdhadev Chakraborty +6
Intracellular phagosomes have a lipid bilayer encapsulated fluidic shell outside the particle, on the outer side of which, molecular motors are attached. An optically trapped spher…
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…
Emergent dynamics due to chemo-hydrodynamic self-interactions in active polymers
Manoj Kumar, Aniruddh Murali, Arvin Gopal Subramaniam +2
The field of synthetic active matter has, thus far, been led by efforts to create point-like, isolated (yet interacting) self-propelled objects (\emph{e.g.} colloids, droplets, mic…
