Simulations of driven overdamped frictionless hard spheres

Computer Physics Communications, 2013
We introduce an event-driven simulation scheme for overdamped dynamics of frictionless hard spheres subjected to external forces, neglecting hydrodynamic interactions.

Hard spheres: crystallization and glass formation [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2009
Motivated by old experiments on colloidal suspensions, we report molecular dynamics simulations of assemblies of hard spheres, addressing crystallization and glass formation. The simulations cover wide ranges of polydispersity s (standard deviation of the particle size distribution divided by its mean) and particle ...

Colloidal hard spheres: Triumphs, challenges, and mysteries

Reviews of Modern Physics
The simplicity of hard spheres as a model system is deceptive. Although the particles interact solely through volume exclusion, that nevertheless suffices for a wealth of static and dynamical phenomena to emerge, making the model an important target for achieving a comprehensive understanding of matter. In addition, while real colloidal suspensions are

Event-Chain Monte-Carlo Simulations of Dense Soft Matter Systems

Frontiers in Physics, 2021
We discuss the rejection-free event-chain Monte-Carlo algorithm and several applications to dense soft matter systems. Event-chain Monte-Carlo is an alternative to standard local Markov-chain Monte-Carlo schemes, which are based on detailed balance, for ...

Polydisperse hard spheres at a hard wall [PDF]

The Journal of Chemical Physics, 2004
The structural properties of polydisperse hard spheres in the presence of a hard wall are investigated via Monte Carlo simulation and density functional theory (DFT). Attention is focused on the local density distribution ρ(σ,z), measuring the number density of particles of diameter σ at a distance z from the wall.

Differences in plasticity between hard and soft spheres

Physical Review Research, 2020
Contact changes in packings of sheared hard spheres invariably trigger instabilities and irreversible rearrangements, providing an archetypal scenario for plasticity of disordered media.

Vanadium‐modified hard carbon spheres with sufficient pseudographitic domains as high‐performance anode for sodium‐ion batteries

Carbon Energy, 2023
Hard carbons are promising anode materials for sodium‐ion batteries. To meet practical requirements, searching for durable and conductive carbon with a stable interface is of great importance.

Ternary Mixtures of Hard Spheres and Their Multiple Separated Phases

Molecules, 2023
We study the liquid phase behavior of ternary mixtures of monodisperse hard spheres in solution. The interactions are modeled in terms of the second virial coefficient and can be additive hard sphere (HS) or non-additive hard sphere (NAHS) interactions ...

Towards Predicting Partitioning of Enzymes between Macromolecular Phases: Effects of Polydispersity on the Phase Behavior of Nonadditive Hard Spheres in Solution

Molecules, 2022
The ability to separate enzymes, or cells or viruses, from a mixture is important and can be realized by the incorporation of the mixture into a macromolecular solution.
