Phase discovery with active learning: Application to structural phase transitions in equiatomic NiTi

no code implementations10 Jan 2024 Jonathan Vandermause, Anders Johansson, Yucong Miao, Joost J. Vlassak, Boris Kozinsky

Here, we train four machine-learned force fields for equiatomic NiTi based on the LDA, PBE, PBEsol, and SCAN DFT functionals.

Active Learning

Learning Interatomic Potentials at Multiple Scales

no code implementations20 Oct 2023 Xiang Fu, Albert Musaelian, Anders Johansson, Tommi Jaakkola, Boris Kozinsky

When running MD, the MTS integrator then evaluates the smaller model for every time step and the larger model less frequently, accelerating simulation.

Scaling the leading accuracy of deep equivariant models to biomolecular simulations of realistic size

1 code implementation20 Apr 2023 Albert Musaelian, Anders Johansson, Simon Batzner, Boris Kozinsky

This work brings the leading accuracy, sample efficiency, and robustness of deep equivariant neural networks to the extreme computational scale.

Learning Local Equivariant Representations for Large-Scale Atomistic Dynamics

3 code implementations11 Apr 2022 Albert Musaelian, Simon Batzner, Anders Johansson, Lixin Sun, Cameron J. Owen, Mordechai Kornbluth, Boris Kozinsky

This work introduces Allegro, a strictly local equivariant deep learning interatomic potential that simultaneously exhibits excellent accuracy and scalability of parallel computation.
