Dynamics and stability of inertial flexible chains under follower activity
Sattwik Sadhu, Nitin Kriplani, Raghunath Chelakkot
The dynamics of flexible polymers and chains under follower activity is known to produce diverse nonequilibrium states. A prominent feature of such systems is the emergence of peri…
Modulating hydrodynamic flow by modifying the active patch of a colloid
Om Vandra, Suhal Siva Ratan T. N., Hemant Giri +4
We have developed a simulation model to study the hydrodynamic flow fields around Brownian colloidal particles with an active surface patch. Hydrodynamics is introduced by modeling…
Dynamics of Marangoni-Driven Elliptical Janus Particles
Pabitra Masanta, Ratan Sarkar, Punit Parmananda +1
We investigate the spontaneous motion of an elliptical Janus particle, driven by Marangoni forces, on a water surface to understand how particle shape and size influence its dynami…
Active chain spirograph: Dynamic patterns formed in extensible chains due to follower activity
Sattwik Sadhu, Nitin Kriplani, Anirban Sain +1
Follower activity results in a large variety of conformational and dynamical states in active chains and filaments. These states are formed due to the coupling between chain geomet…
Active wetting transitions induced by rotational noise at solid interfaces
Suchismita Das, Raghunath Chelakkot
We investigate the wetting transitions displayed by the collection of active Brownian particles (ABPs) confined within rigid, impenetrable, flat walls. In our computational study u…
Kinetically arrested clusters in active filament arrays
Sonu Karayat, Prashant K. Purohit, L. Mahadevan +2
We use Brownian dynamics simulations and theory to study the over-damped spatiotemporal dynamics and pattern formation in a fluid-permeated array of equally spaced, active, elastic…
