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…
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…
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…
Chirality, confinement and dimensionality govern re-entrant transitions in active matter
Anweshika Pattanayak, Amir Shee, Debasish Chaudhuri +1
The non-equilibrium dynamics of individual chiral active particles underpin the complex behavior of chiral active matter. Here we present an exact analytical framework, supported b…
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…
