Self-Organized States from Solutions of Active Ring Polymers in Bulk and under Confinement

JP Miranda, E Locatelli, C Valeriani - Journal of Chemical Theory …, 2023 - ACS Publications
In the present work, we study, by means of numerical simulations, the structural and
dynamical behavior of a suspension of active ring polymers in bulk and under lateral …

Anomalous diffusion of active Brownian particles in responsive elastic gels: Nonergodicity, non-Gaussianity, and distributions of trapping times

K Goswami, AG Cherstvy, A Godec, R Metzler - Physical Review E, 2024 - APS
Understanding actual transport mechanisms of self-propelled particles (SPPs) in complex
elastic gels—such as in the cell cytoplasm, in in vitro networks of chromatin or of F-actin …

Active polar ring polymer in shear flow—An analytical study

RG Winkler, SP Singh - The Journal of Chemical Physics, 2024 - pubs.aip.org
We theoretically study the conformational and dynamical properties of semiflexible active
polar ring polymers under linear shear flow. A ring is described as a continuous semiflexible …

Coil-to-globule collapse of active polymers: a Rouse perspective

P Malgaretti, E Locatelli, C Valeriani - Molecular Physics, 2024 - Taylor & Francis
We derive an effective Rouse model for tangentially active polymers, characterised by a
constant active force tangent to their backbone. In particular, we show that, once extended to …

A passive star polymer in a dense active bath: insights from computer simulations

RS Yadav, S Sharma, R Metzler, R Chakrabarti - Soft matter, 2024 - pubs.rsc.org
Using computer simulations in two dimensions (2D), we explore the structure and dynamics
of a star polymer with three arms made of passive monomers immersed in a bath of active …

Slender phoretic loops and knots

P Katsamba, MD Butler, L Koens… - Physical Review …, 2024 - APS
We present an asymptotic theory for solving the dynamics of slender autophoretic loops and
knots. Our formulation is valid for nonintersecting three-dimensional center lines, with …

A computer simulation study of a chiral active ring polymer

SK Anand - The Journal of Chemical Physics, 2024 - pubs.aip.org
We investigate a ring polymer under the influence of chiral active Brownian forces in two
dimensions using coarse-grained computer simulations. We observe a non-monotonic …

Optothermally Induced Active and Chiral Motion of the Colloidal Structures

R Chand, A Shukla, S Boby, GV Kumar - arXiv preprint arXiv:2411.12488, 2024 - arxiv.org
Artificial soft matter systems have appeared as important tools to harness mechanical motion
for microscale manipulation. Typically, this motion is driven either by the external fields or by …

The influence of active agent motility on SIRS epidemiological dynamics

R Kailasham, AS Khair - arXiv preprint arXiv:2406.01865, 2024 - arxiv.org
Active Brownian disks moving in two dimensions that exchange information about their
internal state stochastically are chosen to model epidemic spread in a self-propelled …
