Exact dynamics and dimensional effects in torque-driven trapped active Brownian particles
Anweshika Pattanayak, Amir Shee, Abhishek Chaudhuri +1
The interplay of chirality, self-propulsion, and confinement generates pronounced non-equilibrium fluctuations, with higher-order moments encoding the shape of the position distrib…
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…
Dynamical metastability and re-entrant localization of trapped active elements with speed and orientation fluctuations
Manish Patel, Amir Shee, Debasish Chaudhuri
We explore the dynamics of active elements performing persistent random motion with fluctuating active speed and in the presence of translational noise in a -dimensional harmoni…
UNC-104 transport properties are robust and independent of changes in its cargo binding
Amir Shee, Vidur Sabharwal, Sandhya P. Koushika +2
Cargo distribution within eukaryotic cells relies on the active transport mechanisms driven by molecular motors. Despite their critical role, the intricate relationship between mot…
Active Brownian particle under stochastic position and orientation resetting in a harmonic trap
Amir Shee
We present an exact analytical study of an Active Brownian Particle (ABP) subject to both position and orientation stochastic resetting in a two-dimensional harmonic trap. Utilizin…
Impact of chirality on active Brownian particle: Exact moments in two and three dimensions
Anweshika Pattanayak, Amir Shee, Debasish Chaudhuri +1
In this work, we investigate the effects of chirality, accounting for translational diffusion, on active Brownian particles in two and three dimensions. Despite the inherent comple…

Self-propulsion with speed and orientation fluctuation: exact computation of moments and dynamical bistabilities in displacement
Amir Shee, Debasish Chaudhuri
We consider the influence of active speed fluctuations on the dynamics of a -dimensional active Brownian particle performing a persistent stochastic motion. We use the Laplace t…
Active Brownian motion with speed fluctuations in arbitrary dimensions: exact calculation of moments and dynamical crossovers
Amir Shee, Debasish Chaudhuri
We consider the motion of an active Brownian particle with speed fluctuations in d-dimensions in the presence of both translational and orientational diffusion. We use an Ornstein-…
Filament-motor protein system under loading: instability and limit cycle oscillations
Amir Shee, Subhadip Ghosh, Debasish Chaudhuri
We consider the dynamics of a rigid filament in a motor protein assay under external loading. The motor proteins are modeled as active harmonic linkers with tail ends immobilized o…
Semiflexible polymer in a gliding assay: reentrant transition, role of turnover and activity
Amir Shee, Nisha Gupta, Abhishek Chaudhuri +1
We consider a model of an extensible semiflexible filament moving in two dimensions on a motility assay of motor proteins represented explicitly as active harmonic linkers. Their h…
Active Brownian particles: mapping to equilibrium polymers and exact computation of moments
Amir Shee, Abhishek Dhar, Debasish Chaudhuri
It is well known that path probabilities of Brownian motion correspond to the equilibrium configurational probabilities of flexible Gaussian polymers, while those of active Brownia…
