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…
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…
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…
