Self-propulsion of active droplets without liquid-crystalline order
Rajesh Singh, Elsen Tjhung, Michael E. Cates
The swimming of cells, far from any boundary, can arise in the absence of long-range liquid-crystalline order within the cytoplasm, but simple models of this effect are lacking. He…
Controlled Optofluidic Crystallization of Colloids Tethered at Interfaces
Alessio Caciagli, Rajesh Singh, Darshana Joshi +2
We report experiments that show rapid crystallization of colloids tethered to an oil-water interface in response to laser illumination. This light-induced transition is due to a co…
Ritz method for transition paths and quasipotentials of rare diffusive events
Lukas Kikuchi, Rajesh Singh, Mike E. Cates +1
The probability of trajectories of weakly diffusive processes to remain in the tubular neighbourhood of a smooth path is given by the Freidlin-Wentzell-Graham theory of large devia…
Periodic Orbits of Active Particles induced by Hydrodynamic Monopoles
Austen Bolitho, Rajesh Singh, R. Adhikari
Terrestrial experiments on active particles, such as Volvox, involve gravitational forces, torques and accompanying monopolar fluid flows. Taking these into account, we analyse the…
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…
Hydrodynamically interrupted droplet growth in scalar active matter
Rajesh Singh, M. E. Cates
Suspensions of spherical active particles often show microphase separation. At a continuum level, coupling their scalar density to fluid flow, there are two distinct explanations.…
