    Machine learning is used to extract essential pattern from big data. This technique can be used to extract the essential feature of quantum many-body wave function (=a vector with exponentially large dimensions), and to obtain compact representation of many-body states. In this article, we review representations of many-body states using Boltzmann machine, a type of artificial neural network. We introduce an efficient representation using restricted Boltzmann machines (RBM) and also discuss the efforts to improve the RBM wave functions.

    Strongly correlated electron materials containing transition metals and/or rare earth elements exhibit various functional properties that are useful in practical applications, such as permanent magnets with high coercivity and high-temperature superconductivity. Although it is expected that the development of materials will become more efficient if these properties can be reproduced and predicted by calculations, they have not yet reached a practical level due to the difficulty in dealing with strong interactions between electrons (quantum many-body effect). In this study, we focus on "multipole ordering," which is one of the phase transitions observed in strongly correlated materials. By combining first-principles calculations based on density functional theory and quantum many-body calculations based on the dynamical mean-field method, we succeeded in reproducing multipole ordering in actual compounds.

    This study aimed to establish a new numerical method for strongly correlated electron systems based on a novel approach combining machine learning schemes with first principles and quantum many-body calculations. Specifically, we focused on 1) development of numerical methods, 2) verification of the accuracy of the developed methods, and 3) application to strongly correlated electron systems. As for 1 and 2, we successfully established a deep learning model incorporating quantum and thermal fluctuations at finite temperatures by combining the artificial neural network method with the physics concept of "purification." As an achievement of 3, we studied the electronic states of strongly correlated ferromagnetic metals and discovered an unusual quantum correlation in a paramagnetic phase.

    Strongly correlated electron compounds offers various practically useful functionalities such as magnetism and superconductivity. The susceptibility represents the response to an external field, and plays an important role in understanding their physical properties. However, calculations of the susceptibility for realistic strongly correlated compounds have not been realized due to the difficulty in numerical calculations. Applying data science approaches, this project has achieved important progress toward the realization of susceptibility calculations for strongly correlated compounds.

    In strongly correlated materials, which exhibit various functional properties such as magnetism and superconductivity, electronic degrees of freedom are closely intertwined with phonon (lattice vibration) degrees of freedom. However, the role of phonons in strongly correlated materials remains largely unexplored. The purpose of this study was to advance our understanding of the interplay between electron and phonon degrees of freedom in strongly correlated systems. In this study, we developed a powerful solver for electron-phonon-coupled models using machine learning, and laid the foundation for understanding the phonon degrees of freedom in real materials. In addition, we have obtained important implications showing the possibility of enhancing superconductivity by controlling the lattice structure in the recently discovered nickel oxide superconductors.

    We established a standard method for ab initio calculation of strongly correlated electron systems and released the codes as open source software. By introducing machine learning methods, most accurate quantum many-body solver in the world was developed and applied to reveal the nature of quantum spin liquids. The machine learning was also developed to extract hidden physical quantities from spectroscopic data. These are the achievement beyond the original research plan. The developed methods were applied to copper-oxide high-Tc superconductors and molecular solids and the experimental phase diagrams were quantitatively reproduced without adjustable parameters, which enabled discovery of the role of electron and spin fractionalization in the mechanism and emergence of superconductivity and quantum spin liquids. The discovery was endorsed by the machine learning analysis of the spectroscopic experimental data and has shown the power of the integrated spectroscopy analyses.

    アルカリ金属をドープしたフラーレン化合物の超伝導について第一原理による研究を行った。この系においては、s波超伝導に隣接してモット絶縁体相が存在するが、それに対する統一的理解はこれまでなされてこなかった。本研究においては、第一原理計算により、フェルミエネルギー近傍のバンドと格子振動（フォノン）の自由度を含んだ低エネルギー有効ハミルトニアンを導出した。有効的な電子間相互作用はクーロン相互作用（斥力）とフォノンを媒介とする相互作用（引力）の和で表される。密度密度型の相互作用は前者がはるかに大きいのに対し、交換相互作用においてはフォノン媒介の引力が上回り、有効的に負の交換相互作用及びペア・ホッピング相互作用が実現していることが第一原理計算により明らかになった。 得られたハミルトニアンを拡張動的平均場理論で解析することにより、s波超伝導相にモット絶縁体相が隣接した相図を理論的に再現することに成功した。また、超伝導転移温度に関しても理論により得られた最高転移温度は28 K程度と、実験の35 Kを非常によく再現することがわかった。詳細な解析により、超伝導の本質は 1. 負の交換相互作用に対応して軌道間斥力が軌道内斥力が大きくなることによる軌道内ペアの生成 2. ペア・ホッピング相互作用による軌道内ペアの他の軌道への散乱（スール・近藤機構） であることが明らかになった。負の交換相互作用が実現するのはフォノンの存在によるので、この超伝導にはフォノンが本質的な役割を果たしている。しかしながら、従来型のフォノン超伝導と違うのは、強相関効果が超伝導を助ける点にある。相関効果によって電子の運動エネルギーが減少することにより１の機構がより有効的に働くためである。よって、フラーレン超伝導体はフォノンと電子相関が協力しあって高温s波超伝導を実現しているような全く新しいタイプの超伝導体であることがわかった。
