confined by a harmonic potential and interacting with a suspension of active Brownian …

Active and thermal fluctuations in multi-scale polymer structure and dynamics

A Ghosh, AJ Spakowitz - Soft Matter, 2022 - pubs.rsc.org
The presence of athermal noise or biological fluctuations control and maintain crucial life-
processes. In this work, we present an exact analytical treatment of the dynamic behavior of …

Statistical behavior of nonequilibrium and living biological systems subjected to active and thermal fluctuations

A Ghosh, AJ Spakowitz - Physical Review E, 2022 - APS
We present a path-integral formulation of the motion of a particle subjected to fluctuating
active and thermal forces. This general framework predicts the statistical behavior …

Periodic potential can enormously boost free-particle transport induced by active fluctuations

K Białas, J Łuczka, J Spiechowicz - Physical Review E, 2023 - APS
Active fluctuations are detected in a growing number of systems due to self-propulsion
mechanisms or collisions with an active environment. They drive the system far from …

Work distribution of a colloid in an elongational flow field and under Ornstein-Uhlenbeck noise

D Saha, R Sharma - Physical Review E, 2024 - APS
The study of thermodynamic properties of microscopic systems, such as a colloid in a fluid,
