Direct verification of the fluctuation-dissipation relation in viscously coupled oscillators
Shuvojit Paul, Abhrajit Laskar, Rajesh Singh +3
The fluctuation-dissipation relation, a central result in non-equilibrium statistical physics, relates equilibrium fluctuations in a system to its linear response to external force…
Filament actuation by an active colloid at low Reynolds number
Abhrajit Laskar, R. Adhikari
Active colloids and externally actuated semi-flexible filaments provide basic building blocks for designing autonomously motile micro-machines. Here, we show that a passive semi-fl…
Brownian microhydrodynamics of active filaments
Abhrajit Laskar, R. Adhikari
Slender bodies capable of spontaneous motion in the absence of external actuation in an otherwise quiescent fluid are common in biological, physical and technological contexts. The…
Hydrodynamic Instabilities Provide A Generic Route To Spontaneous Biomimetic Oscillations In Chemomechanically Active Filaments
Abhrajit Laskar, Rajeev Singh, Somdeb Ghose +3
Non-equilibrium processes which convert chemical energy into mechanical motion enable the motility of organisms. Bundles of inextensible filaments driven by energy transduction of…
Autonomous Motility of Active Filaments due to Spontaneous Flow-Symmetry Breaking
Gayathri Jayaraman, Sanoop Ramachandran, Somdeb Ghose +4
We simulate the nonlocal Stokesian hydrodynamics of an elastic filament which is active due a permanent distribution of stresslets along its contour. A bending instability of an in…
