氏名:鈴木 恒雄

所属:大阪大学核物理研究センター(RCNP)グループ

概要:核物理研究センターでは、サブアトミック世界の強い相互作用の基本原理である量子色力学(QCD)を中心に、素粒子・ハドロン・原子核物理学とその関連分野にわたる研究を、全国の共同利用研究者とともに行っている。スーパーコンピューターは、大規模計算を必要とする理論的な研究に使われている。その内容は、格子QCDによる数値シミュレーション、原子核構造及びハドロン物理現象論の数値的な解法である。
(i) 格子QCD

ハドロン分光学(質量などの計算)とハドロン間相互作用、クォーク間相互作用、有限温度・密度における真空の性質、閉じ込め・カイラル対称性の問題

(ii) 少数多体系・ハドロン物理現象論

3-4核子系の精密計算、ハドロン生成反応の理論解析に基づくハドロン共鳴

(iii) 核構造

原子核密度汎関数法

(iv) その他

2次元格子フェルミオン系、超新星爆発、弦理論
