物性物理と情報学における計算論的アプローチの開発とその応用
(English)
Development of Computational Approach for Condensed-Matter Physics and Informatics and its Application
Overview of the research
(Japanese)
物性物理や情報学における重要な未解決問題を研究するために、強く相互に作用する要素からなるシステムに対する計算論的アプローチの進化させてきた。例えば、量子モンテカルロ法をもちいることで、量子物質の風変わりな相転移現象やその臨界性を研究することができる。また、要素間の絡み合いを操作する技術は量子系や古典系の不思議な性質を研究するのに役立ち、絡み合いをシステマティックに処理するテンソルネットワーク法の改良を行ってきた。さらに、最新の情報技術は物理におけるデータ解析に応用可能である。例えば、ベイズ推定の枠組みを臨界現象のスケーリング解析に導入することで未知のユニーバサリティークラスの決定が精度よく可能になった。
(English)
I advance computational approach for the study of strongly correlated systems to attack critical open problems in condensed-matter physics and informatics. Using quantum Monte Carlo, we can study the exotic phase transition and criticality of quantum matter. A technique to manipulate entanglement is useful for a study of mysterious property in quantum and classical systems. I study a further development of tensor network schemes for processing entanglement. A new information technique can be applied to the numerical analysis in physics. Introducing a Bayesian inference method in the finite-size scaling analysis of criticality, we can determine the new universality of unknown systems precisely.
