Characterizing exact dynamics of a trapped active Brownian particle under torque in two and three dimensions
Anweshika Pattanayak, Amir Shee, Abhishek Chaudhuri +1
The interplay of chirality, self-propulsion, and spatial confinement generates striking non-equilibrium fluctuations whose higher-order statistics carry information about the dynam…
From spirals to flagellar beating: How pivot-like defects control semiflexible filament dynamics in motility assays
Sandip Roy, Debasish Chaudhuri, Abhishek Chaudhuri
We demonstrate that internal pivot-like defects, arising from rigor mutant motor proteins that bind without stepping, fundamentally reshape the dynamics of semiflexible filaments i…
Role of activity and dissipation in achieving precise beating in cilia: Insights from the rower model
Subhajit Gupta, Debasish Chaudhuri, Supravat Dey
Cilia and flagella are micron-sized filaments that actively beat with remarkable precision in a viscous medium, driving microorganism movement and efficient flow. We study the rowe…
Activated solids: Spontaneous deformations, non-affine fluctuations, softening, and failure
Parswa Nath, Debankur Das, Surajit Sengupta +1
Internal activity can fundamentally reshape the mechanical behavior of solids, yet its role in softening and failure remains incompletely understood. In this study, we investigate…
