Computational investigation of microgels: synthesis and effect of the microstructure on the deswelling behavior

AJ Moreno, FL Verso - Soft Matter, 2018 - pubs.rsc.org
We present computer simulations of a realistic model of microgels. Unlike the regular
network frameworks usually assumed in the simulation literature, we model and simulate a …

Nonuniversal aging during phase separation with long-range interaction

S Ghosh, SK Das - Physical Review E, 2024 - APS
Issues concerning the kinetics of phase transitions are not well established for the cases
where the order parameter remains conserved with time, particularly when the interatomic …

Kinetics of polymer collapse: Effect of temperature on cluster growth and aging

S Majumder, J Zierenberg, W Janke - Soft matter, 2017 - pubs.rsc.org
Using state of the art Monte Carlo simulations of a bead-spring model we investigate both
the equilibrium and the nonequilibrium behavior of the homopolymer collapse. The …

Nonuniversality of Aging during Phase Separation of the Two-Dimensional Long-Range Ising Model

F Müller, H Christiansen, W Janke - Physical Review Letters, 2024 - APS
We investigate the aging properties of phase-separation kinetics following quenches from
T=∞ to a finite temperature below T c of the paradigmatic two-dimensional conserved Ising …

Growth and aging in a few phase-separating active matter systems

F Dittrich, J Midya, P Virnau, SK Das - Physical Review E, 2023 - APS
Via computer simulations we study evolution dynamics in systems of continuously moving
active Brownian particles. The obtained results are discussed against those from the passive …

Phase behavior and dynamics of active Brownian particles in an alignment field

S Othman, J Midya, T Auth, G Gompper - Physical Review E, 2025 - APS
Self-propelled particles that are subject to noise are a well-established generic model
system for active matter. A homogeneous alignment field can be used to orient the direction …

Finite-size scaling in kinetics of phase separation in certain models of aligning active particles

T Paul, N Vadakkayil, SK Das - Physical Review E, 2024 - APS
To study the kinetics of phase separation in active matter systems, we consider models that
impose a Vicsek-type self-propulsion rule on otherwise passive particles interacting via the …

Reverse-engineering method for XPCS studies of non-equilibrium dynamics

A Ragulskaya, V Starostin, N Begam, A Girelli… - IUCrJ, 2022 - journals.iucr.org
X-ray photon correlation spectroscopy (XPCS) is a powerful tool in the investigation of
dynamics covering a broad time and length scale. It has been widely used to probe …

Pattern, growth, and aging in aggregation kinetics of a Vicsek-like active matter model

SK Das - The Journal of chemical physics, 2017 - pubs.aip.org
Via molecular dynamics simulations, we study kinetics in a Vicsek-like phase-separating
active matter model. Quantitative results, for isotropic bicontinuous pattern, are presented on …
