Temporally correlated active forces drive segregation and enhanced dynamics in chromosome polymers

S Brahmachari, T Markovich, FC MacKintosh… - PRX Life, 2024 - APS
Understanding the mechanisms governing the structure and dynamics of flexible polymers
like chromosomes, especially the signatures of motor-driven active processes, is of great …

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 …

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 …

Spiral and helical formation of passive and active polymers with stiffness heterogeneity in a spherical cavity

R Yan, S Liu, N Zhao - Soft Matter, 2025 - pubs.rsc.org
Biomolecules usually adopt ubiquitous circular structures which are important for their
functionality. Based on three-dimensional Langevin dynamics simulations, we investigate …
