■ 主な研究テーマ・活動
(1)高エネルギー原子核衝突の物理・媒質中でのハドロンの研究
(2)有限量子多体系の理論的研究

■ 研究についてのPR
(1) ハドロンとは,強い相互作用する素粒子(陽子や中性子や中間子)のことです。重い原子核同士を高いエネルギーで衝突させて,宇宙初期(宇宙開闢から0.0001秒程度)に経験したであろう高温または高密度状態を実験的に実現しようという試みがなされていますが,そのような状態での基本粒子(クォーク・グルオン)や素粒子の振る舞い,物質の相転移,自然界が持っている対称性の様子等について理論的に研究しています。
(2) 有限個の核子(陽子・中性子の総称)からなる多粒子系としての原子核を代表に,ミクロの世界で現れる量子力学的な揺らぎの効果や,熱による揺らぎの効果をどのようにして理論的にうまく取り込むかを研究しています。ハドロン物理学研究での相転移現象の研究との関係からも,システムの時間発展を考えに入れて研究しています。
