L Theeyancheri, S Chaki, T Bhattacharjee… - The Journal of …, 2023 - pubs.aip.org
To understand the dynamical and conformational properties of deformable active agents in
porous media, we computationally investigate the dynamics of linear chains and rings made …

Dynamic clustering of active rings

L Theeyancheri, S Chaki, T Bhattacharjee… - Physical Review …, 2024 - APS
A collection of rings made of active Brownian particles (ABPs) for different packing fractions
and activities is investigated using computer simulations. We show that active rings display …

Effect of local active fluctuations on structure and dynamics of flexible biopolymers

S Dutta, A Ghosh, AJ Spakowitz - Soft Matter, 2024 - pubs.rsc.org
Active fluctuations play a significant role in the structure and dynamics of biopolymers (eg
chromatin and cytoskeletal proteins) that are instrumental in the functioning of living cells …

Delayed excitations induce polymer looping and coherent motion

A Goychuk, D Kannan, M Kardar - Physical Review Letters, 2024 - APS
We consider inhomogeneous polymers driven by energy-consuming active processes which
encode temporal patterns of athermal kicks. We find that such temporal excitation programs …

Effects of active noise on transition-path dynamics

K Goswami, R Metzler - Journal of Physics: Complexity, 2023 - iopscience.iop.org
We propose an extension of the existing model describing a biomolecular reaction such as
protein folding or ligand binding which is usually visualised as the barrier crossing of a …

Enhanced diffusion and universal Rouse-like scaling of an active polymer in poor solvent

S Majumder, S Paul, W Janke - Physical Review Materials, 2024 - APS
By means of Brownian dynamics simulations we study the steady-state dynamic properties
of a flexible active polymer in a poor solvent condition. Our results show that the effective …

Trapped tracer in a non-equilibrium bath: dynamics and energetics

K Goswami, R Metzler - Soft Matter, 2023 - pubs.rsc.org
We study the dynamics of a tracer that is elastically coupled to active particles being kept at
two different temperatures, as a prototype of tracer dynamics in a non-equilibrium bath …

Escape dynamics of active ring polymers in a cylindrical nanochannel

C Li, Q Chen, M Ding - Soft Matter, 2024 - pubs.rsc.org
We explore the escape dynamics of active ring polymers confined in a cylindrical
nanochannel using Brownian dynamics. Our simulation results show that the escape time …

Structure and dynamics of an active polymer chain inside a nanochannel grafted with polymers

R Sahoo, R Chakrabarti - Soft Matter, 2023 - pubs.rsc.org
We use computer simulations to investigate the complex dynamics of a polymer, made of
active Brownian particles, inside a channel grafted internally with passive polymer chains …

A review of active matter reviews

M Vrugt, R Wittkowski - arXiv preprint arXiv:2405.15751, 2024 - arxiv.org
In the past years, the amount of research on active matter has grown extremely rapidly, a fact
that is reflected in particular by the existence of more than 600 review articles on this topic …
