高温超伝導体などの強相関量子多体系の性質を、ミクロの立場から説明できる理論モデルはまだ存在しません。このような量子多体系では、強結合効果が重要になりますが、超弦理論から登場したAdS/CFT双対性の発見によって、強結合の場の理論が重力理論によって説明できる可能性が出てきました。本研究室では、このAdS/CFT双対性を利用して、曲がった時空上での重力の計算から、強相関2次元電子系の物理や相対性理論に関する基礎的問題を解明していきます。

■教員研究テーマ
超弦理論から登場したAdS/CFT対応を利用して、ブラックホール内部にある時空特異点がどのようにゲージ理論で見えるのかを探ったり、逆に重力理論を応用して、ゲージ理論プラズマに登場する様々な輸送係数の導出を試みている。最近では、AdS/CFT対応の物性理論への応用にも興味を持って研究している
