Overdamped Lattice Dynamics of Sedimenting Active Cosserat Crystals
Austen Bolitho, Ronojoy Adhikari
Micropolar active matter requires for its kinematic description both positional and orientational degrees of freedom. Activity generates dynamic coupling between these kinematic va…
Stokes traction on an active particle
Günther Turk, Rajesh Singh, Ronojoy Adhikari
The mechanics and statistical mechanics of a suspension of active particles are determined by the traction (force per unit area) on their surfaces. Here we present an exact solutio…
PyStokes: phoresis and Stokesian hydrodynamics in Python
Rajesh Singh, R. Adhikari
We present a modular Python library for computing many-body hydrodynamic and phoretic interactions between spherical active particles in suspension, when these are given by solutio…
Internal friction controls active ciliary oscillations near the instability threshold
Debasmita Mondal, Ronojoy Adhikari, Prerna Sharma
Ciliary oscillations driven by molecular motors cause fluid motion at micron scale. Stable oscillations require a substantial source of dissipation to balance the energy input of m…
Competing chemical and hydrodynamic interactions in autophoretic colloidal suspensions
Rajesh Singh, R. Adhikari, M. E. Cates
At the surfaces of autophoretic colloids, slip velocities arise from local chemical gradients that are many-body functions of particle configuration and activity. For rapid chemica…
Flow-induced phase separation of active particles is controlled by boundary conditions
Shashi Thutupalli, Delphine Geyer, Rajesh Singh +2
Active particles, including swimming microorganisms, autophoretic colloids and droplets, are known to self-organize into ordered structures at fluid-solid boundaries. The entrainme…
