Outline of Final Research Achievements

We developed open-source softwares implementing continuous-time quantum impurity solvers based on the interaction-expansion and hybridization-expansion algorithms. We developed a new algorithm for numerical analytic continuation of quantum Monte Carlo data to spectral functions. We found a new basis set for representing imaginary-time dependence of Matsubara Green's functions. The new basis greately reduces memory footprints of quantum many-body calculations. We developed an open-source software for computing properties of strongly correlated electronic systems "DCore" based on dynamical mean-field theory.

Academic Significance and Societal Importance of the Research Achievements

電子間の強い斥力から非自明な量子多体現象が生じる。遷移金属酸化物は、その舞台として近年精力的に研究されている。本研究計画では、その物性を第一原理計算から明らかにする基礎技術が成果として得られた。特に、動的平均場近似法に基づく計算において必須となる高性能な量子不純物ソルバーの開発、スペクトル関数の推定技術が開発された。また、温度グリーン関数をコンパクトに表現する新しい方法論が開発された。現実の物質の物性の効率的な計算や実験との比較において重要な技術である。
