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…
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…
Optimal transport and control of an active particle near a plane wall
Utkarsh Maurya, Kavya Swaminathan, Ejaz Ashraf +1
The control of active colloidal particles via optical traps is a cornerstone for research of matter at the micron and nanometer scale. A central challenge in this domain is the der…
