低炭素社会の実現に向け二酸化炭素の削減と環境負荷の小さい水素の利用が求められているが、水素及び二酸化炭素を利用した有機合成反応の構築は未だ不十分だ。有機合成反応における水素と二酸化炭素の利用法として一酸化炭素の代替としての使用が注目されている。一酸化炭素を用いる有機合成法のうち、私は工業的価値の高いアルデヒド合成に着目した。本研究ではNiFe低原子価錯体を用いて穏和な条件下でのアルデヒド合成を狙う [...]

For realization of a plasma thermonuclear reactor, impurity introduced into the core plasma from the wall material is a critical issue to maintain the plasma performance. Experiments have reported tha [...]

量子スピン系において臨界点を数値的に計算する手法は複数提案されているが、多重臨界点付近では精度が悪くなってしまう。本研究ではボンド交代XXZ鎖を扱う。異方性の極限で等価になる横地場イジングモデルに関して、有限系において成り立つ双対変換を導入し境界条件と励起状態の対称の関係性を確認した。それをボンド交代 XXZ 鎖に拡張し、ひねり境界条件を用いて相転移点を計算した。本研究の方法を用いボンド交代 XX [...]
