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…
Spectral Signatures of Active Fluctuations in Semiflexible Polymers
Love Grover, Anil Kumar Dasanna, Abhishek Chaudhuri
We study how an active bath is transduced into the internal fluctuation spectrum of a semiflexible polymer. Starting from the statistics of active forces exerted by an explicit bat…
Non-reciprocal visual perception and polar alignment drive collective states in chiral active particles
Diganta Bhaskar, Abhishek Chaudhuri, Anil Kumar Dasanna
Self-propelled particles rarely move in straight lines; environmental interactions, shape asymmetry, and intrinsic torques generically induce curved or fluctuating trajectories. In…
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…
