Free Webinar with MIT Professor Ju Li: Invention and Applications of Universal Machine Learning Interatomic Potential
USA: Monday, May 29, 2023 at 7:00 – 8:30 pm ET | 4:00 – 5:30 pm PT
Japan: Tuesday, May 30 at 8 – 9:30 am JST
Presented by: Ju Li, Professor at Massachusetts Institute of Technology
Matlantis™ will host a free webinar presented by Ju Li, a professor at the Department of Nuclear Science and Engineering and Department of Materials Science and Engineering at Massachusetts Institute of Technology (MIT), titled The Invention and Applications of Universal Machine Learning Interatomic Potential. The webinar will be held via Zoom at 7 – 8:30 pm Eastern Time (USA) on Friday, May 26, 2023. Registration will be free.
In this webinar, Professor Li will describe the recent invention of a robust universal machine learning interatomic potential that covers much of the periodic table. More than one thousand GPU years were used to generate the ab initio training data guided by active learning. Diverse test simulations have shown this machine learning potential has outstanding performance, with energy error significantly less than the chemical accuracy (43 meV/atom) for even chemically very complex systems. This universal potential, which powers the Matlantis™ atomistic simulator, can run over 10,000 times faster than density functional theory (DFT) when dealing with several thousand atoms, and the latest release allows for more than 10,000 atoms of arbitrary combinations of 72 elements to be simulated together. Going from a few hundred atoms in DFT to up to 55,000 atoms in Matlantis™, one can study realistic microstructures such as extended defects with curvatures and their interactions, realistic phase transformations, plastic deformation and damage evolution, electrochemical interfaces, etc.
Who should attend:
- Computational scientists who are facing limitations of their current calculation/simulation approach
- Researchers who are interested in discovering game-changing new materials using computer simulation
- Anyone who is interested in knowing about what’s happening at the forefront of materials informatics
