Efficient exploration of high-Tc superconductors by a gradient-based composition design

no code implementations20 Mar 2024 Akihiro Fujii, Koji Shimizu, Satoshi Watanabe

We propose a material design method via gradient-based optimization on compositions, overcoming the limitations of traditional methods: exhaustive database searches and conditional generation models.

Enhancing Inverse Problem Solutions with Accurate Surrogate Simulators and Promising Candidates

1 code implementation26 Apr 2023 Akihiro Fujii, Hideki Tsunashima, Yoshihiro Fukuhara, Koji Shimizu, Satoshi Watanabe

In this study, we investigated the impact of surrogate simulators' accuracy on the solutions and discovered that the more accurate the surrogate simulator is, the better the solutions become.

Persistent homology-based descriptor for machine-learning potential of amorphous structures

no code implementations28 Jun 2022 Emi Minamitani, Ippei Obayashi, Koji Shimizu, Satoshi Watanabe

A promising method to achieve this is machine-learning potentials, which is an alternative to computationally demanding ab initio calculations.
