Research Abstract

本年度は最終年度であるので、今迄に導入したワークステーションとスーパーコンピューターを活用し、これ迄の研究のまとめと新しい展開を行った。
磁場中の量子細線の電子状態の研究が安藤と吉岡によって行われ、特に吉岡は「非朝永-Luttinger 液体状態」が出現しうることを示した。
数値繰り込み群の方法は本重点領域によって大きい進展があった。内部構造が重要な希土類の近藤効果(酒井)、超伝導体中の近藤効果(斯波、酒井)に続き、本年は無限大次元ハバード・モデルへの応用が始まった。(酒井、倉本)
量子モンテ・カルロ法については、二次元の強相関系の研究(今田)や無限大次元ハバード・モデルの磁化過程への応用(佐宗)がなされた。
変分モンテ・カルロ法の発展としては、近藤格子への応用がなされた。(岡部)
第1年度から続いている本グループの大きい課題としてはHaldane ギャップ問題への厳密対角化法による研究がある。動的相関関数の詳細な研究(高橋)、隠れたストリング・オーダーの研究(坂井、高橋)、ESRの理論的研究(坂井、斯波)などがなされた。
その他、コンピューターを利用した「一次元超対称t-Jモデル」の研究(倉本、横山)、アブリコソフ構造の数値シミュレーション(永長)なども当グループの成果である。
これらの研究は平成5年度内に開かれた、谷口シンポジウムなどの国際会議のほか、平成6年度に開かれる「磁気国際会議」、「日独セミナー」、「サンタ・バーバラ・ワークショップ」において招待講演として発表されることになっている。
