Impact of torque on active Brownian particle: exact moments in two and three dimensions

A Pattanayak, A Shee, D Chaudhuri… - New Journal of …, 2024 - iopscience.iop.org
In this work, we investigate the effects of torque, accounting for translational diffusion, on
active Brownian particles (ABPs) in two (2d) and three (3d) dimensions. The torque is …

Calorimetry for active systems

P Dolai, C Maes, K Netočný - SciPost Physics, 2023 - scipost.org
We provide the theoretical basis of calorimetry for a class of active particles subject to
thermal noise. Simulating AC-calorimetry, we numerically evaluate the heat capacity of run …

Bouncing dynamics of inertial self-propelled particles reveals directional asymmetry

D Horvath, C Slabý, Z Tomori, A Hovan, P Miskovsky… - Physical Review E, 2023 - APS
This study aims to examine experimental conditions in which active particles are forced by
their surroundings to move forward and backward in a continuous oscillatory manner. The …

Magnetized granular particles running and tumbling on the circle

M Ledesma-Motolinía, JL Carrillo-Estrada, A Escobar… - Physical Review E, 2023 - APS
It has been shown that a nonvibrating magnetic granular system, when fed by an alternating
magnetic field, behaves with most of the distinctive physical features of active matter …

Boundary layers and universal distribution in boundary driven active systems

P Dolai, A Das - arXiv preprint arXiv:2412.20287, 2024 - arxiv.org
We study non-interacting run-and-tumble particles (RTPs) in one dimension driven by
particle reservoirs at the boundaries. Analytical results for the steady state and dynamics are …

Role of kinematic constraints in the time reversal symmetry breaking of a model active matter

S Das, S Ghosh, T Sadhu, JU Klamser - arXiv preprint arXiv:2409.10425, 2024 - arxiv.org
Active-matter systems are inherently out-of-equilibrium and perform mechanical work by
utilizing their internal energy sources. Breakdown of time-reversal symmetry (BTRS) is a …

A Pattanayak, A Shee, D Chaudhuri… - arXiv preprint arXiv …, 2024 - arxiv.org
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 complexity in …

Top-down and bottom-up models of collective motion

HL Devereux - 2022 - wrap.warwick.ac.uk
Active matter is an expanding field of physics covering a diverse range of complex and
beautiful phenomena. From examples we see in our everyday lives, such as the flight of …
