Optimized utilization of COMB3 reactive potentials in LAMMPS [PDF]

open access: yesThe Journal of Chemical Physics, 2020
An investigation to optimize the application of the third-generation charge optimized many-body (COMB3) interatomic potential and associated input parameters was carried out through the study of solid–liquid interactions in classical molecular dynamics simulations.

ENABLING ACCURATE THERMAL TRANSPORT CALCULATIONS IN LAMMPS

open access: yes, 2020
Molecular dynamics (MD) simulations are used extensively to study thermal transport in materials, and one of the most widely used MD software packages is LAMMPS. However, the most common MD technique to compute thermal conductivity, the Green-Kubo method,

Molecular Dynamics Analysis of Temperature and Shear Stress Effects on Nickel Bi-Crystal Amorphization [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering
Atomic amorphization in bi-crystals, marked by a loss of long-range order, is typically induced by factors such as high-energy atom irradiation, mechanical deformation, or thermal processes.

Evaluation of Machine Learning Interatomic Potentials for Gold Nanoparticles—Transferability towards Bulk

open access: yesNanomaterials, 2023
We analyse the efficacy of machine learning (ML) interatomic potentials (IP) in modelling gold (Au) nanoparticles. We have explored the transferability of these ML models to larger systems and established simulation times and size thresholds necessary ...

Dynamic in situ control of heat rectification in graphene nano-ribbons using voltage-controlled strain

open access: yesFrontiers in Nanotechnology
An increasing number of papers propose routes to implement thermal counterparts of electronic rectification. These schemes are mainly based on combinations of crystal anharmonicity and broken mirror symmetry.
