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…
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…
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…
Self-organized fractal architectures driven by motility-dependent chemotactic feedback
Subhashree Subhrasmita Khuntia, Debasish Chaudhuri, Abhishek Chaudhuri
Complex spatial patterns in biological systems often arise through self-organization without a central coordination, guided by local interactions and chemical signaling. In this st…
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…
