Overview of the Webinar | In recent years, the importance of first-principles calculations has increased in material design for catalysts, batteries, semiconductors, etc., but many studies have imposed significant constraints on modeling due to the high calculation costs. There are various approaches to perform material calculations quickly with an accuracy close to that of first-principles calculations, but in most cases the aim is to reproduce a specific system with high accuracy, and the strong parameter dependency and low versatility have been an issue. Neural Network Potential (NNP) is a machine learning model that uses the results of first-principles calculations as training data to infer the energy and force of molecules and crystal structures, making it possible to remove the parameter dependency mentioned above, but previous NNPs were limited in the systems they could target. In this study, we aimed to use NNP to conduct material exploration in various fields, and developed PFP as a new general-purpose NNP that supports 55 elements. In this presentation, we will introduce examples of phenomenon analysis and material design using PFP, and discuss how the possibility of simulation-driven material development has expanded by demonstrating the success of achieving both high speed and accuracy. |
