Polymer glass formation: Role of activation free energy, configurational entropy, and collective motion
WS Xu, JF Douglas, ZY Sun - Macromolecules, 2021 - ACS Publications
We provide a perspective on polymer glass formation, with an emphasis on models in which
the fluid entropy and collective particle motion dominate the theoretical description and data …

A random first-order transition theory for an active glass
How does nonequilibrium activity modify the approach to a glass? This is an important
question, since many experiments reveal the near-glassy nature of the cell interior …

Attractive versus truncated repulsive supercooled liquids: The dynamics is encoded in the pair correlation function
We compare glassy dynamics in two liquids that differ in the form of their interaction
potentials. Both systems have the same repulsive interactions but one has also an attractive …

Escape of a passive particle from an activity-induced energy landscape: emergence of slow and fast effective diffusion
S Chaki, R Chakrabarti - Soft Matter, 2020 - pubs.rsc.org
Spontaneous persistent motions driven by active processes play a central role in
maintaining living cells far from equilibrium. In the majority of research studies, the steady …

A comparative study of the correlation between the structure and the dynamics for systems interacting via attractive and repulsive potentials
We present the study of the structure–dynamics correlation for systems interacting via
attractive Lennard-Jones (LJ) and its repulsive counterpart, the Weeks–Chandler–Andersen …

Noether-constrained correlations in equilibrium liquids
Liquid structure carries deep imprints of an inherent thermal invariance against a spatial
transformation of the underlying classical many-body Hamiltonian. At first order in the …

Microscopic theory of softness in supercooled liquids
MK Nandi, SM Bhattacharyya - Physical Review Letters, 2021 - APS
We introduce a new measure of the structure of a liquid which is the softness of the mean-
field potential developed by us earlier. We find that this softness is sensitive to small …

Identifying structural signature of dynamical heterogeneity via the local softness parameter
In this work we study the relationship between the softness of a mean-field caging potential
and dynamics at the local level. We first describe the local softness, which shows a …

Effective temperature of active fluids and sheared soft glassy materials
The dynamics within active fluids, driven by internal activity of the self-propelled particles, is
a subject of intense study in non-equilibrium physics. These systems have been explored …

Persistent anti-correlations in Brownian dynamics simulations of dense colloidal suspensions revealed by noise suppression
Transport properties of a hard-sphere colloidal fluid are investigated by Brownian dynamics
simulations. We implement a novel algorithm for the time-dependent velocity-autocorrelation …
