Outline of Final Research Achievements

The present research establishes a new framework in quantitative analysis in dynamical correlation functions. It combined the recent developments in quantum inverse scattering method, quantum transfer matrix formalism and form factor expansions. We apply the novel formalism to the quantum spins chains and we successful evaluate static and dynamical correlation functions with high precisions.

Academic Significance and Societal Importance of the Research Achievements

量子相関の理解は、量子力学に基づいたナノテクノロジー、情報通信技術に必須である。これに関して厳密な結果をもたらしたことで、本研究はさらなる技術発展の基礎となりうるものである。相関関数の解析的評価は困難であると理論的にも考えられてきたが、数値計算まで精密に行える枠組みを提示した意義は大きい。
