Outline of Annual Research Achievements

ガラス形成物質に見られるテラヘルツ帯普遍的励起であるボゾンピークやフラクタル構造体の普遍的励起であるフラクトンに関し、テラヘルツ時間領域分光を主とした分光研究を推進した。ボゾンピークに関する基礎的な実験研究と分子動力学計算によって得た知見から、ナノアモルファス領域において系が相分離を起こす場合にボゾンピークも分離することが明らかとなった。これは、高分子のミクロ相分離の系への応用が期待できる。また、ボゾンピーク周波数近傍の誘電関数はローレンツモデルやデバイ緩和モデルで表現できない特異性を持つが、これを克服するためにフォノン-ポラリトンの分散関係において減衰幅に波数依存性を持たせることによって解決した[arXiv:2004.12358]。
フラクトン励起に関し、非晶質に対する線形応答理論とフラクトンモデルの分散関係を組み合わせ、フラクトン領域の赤外光振動結合定数の表式を提案し、タンパク質リゾチームに対するテラヘルツ分光によって検証を行った[arXiv:1910.04400]。このフラクトンを調べるために粗視化分子動力学 計算による予備研究を実施したが[Sci. Rep. 2019]、振動状態密度にフラクトンは発現しなかった。理由は、実施した計算において高分子1本鎖のフラクタル次元は２であるが、系全体のフラクタル次元は３でありフラクタル構造体ではなかったことに由来していると結論した。また、パーシステントホモロジー理論におけるパーシステントホモロジー次元とフラクタル次元を比較し、タンパク質の主鎖に関する2 次（空洞）のパーシステント図から得られるパーシステントホモロジー次元が、フラクタル次元と同様の値を示すことを見出した。
