Semiflexible Ring Polymers on Active Motor Beds: Nonequilibrium Dynamics and Conformations
Sandip Roy, Abhishek Chaudhuri, Anil Kumar Dasanna
A semiflexible ring polymer on a motor-protein bed exhibits activity- and processivity-dependent rotational and conformational dynamics that are not captured by linear-chain behavi…
Inertia-chirality interplay in active Brownian motion: exact dynamics and phase maps
Anweshika Pattanayak, Sandip Roy, Abhishek Chaudhuri
We present an exact, time-resolved theory for a two-dimensional chiral active Brownian particle (cABP) with translational inertia. Using a Laplace-transform moment hierarchy, we de…
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…
Confinement and Activity-Driven Dynamics of Semiflexible Polymers in Motility Assays
Sandip Roy, Abhishek Chaudhuri, Anil Kumar Dasanna
We investigate the nonequilibrium dynamics of semiflexible polymers driven by motor proteins (MPs) in two-dimensional motility assays under harmonic confinement. Using a coarse-gra…
