Fine-tuning ML interatomic potentials via a new LoRA-based Equitrain framework with minimal additional data improves phonon and thermal predictions over base and scratch-trained models in 53 systems.
Thermally curved hBN flakes create strain that suppresses phonon dephasing for defect emitters, achieving Debye-Waller factors of 0.91 and narrower linewidths at room temperature.
pyzentropy implements recursive entropy to compute total system entropy from first-principles supercell calculations, reproducing Invar behavior and experimental phase diagrams for Fe3Pt.
MatterSim delivers a single deep learning force field that simulates inorganic materials across elements, 0-5000 K, and up to 1000 GPa with near first-principles accuracy for lattice dynamics, mechanics, and Gibbs free energies.
MatterSim-MT is a multi-task ML foundation model pretrained on 35M+ structures for in silico materials property prediction and complex simulations.
Machine-learned force fields trained on coupled-cluster potential energy surfaces produce phonon dispersions and vibrational densities of states for solids that agree better with experiment than DFT-based models.
A finite-displacement phonon workflow for MOF-5 demonstrates that spurious imaginary modes can be eliminated by tighter force/grid convergence and careful cell/symmetry choice, with a residual soft A2g mode mapping to a shallow Fm-3 displacive minimum.
