実験室において実現可能な電子プラズマは, 密度や温度や次元の多様にひろがる領域のうちの一部分に限られている. 計算機シミュレーションを用いて, 「現状での実現可能性」という枠をとりはらい, 強結合プラズマの全体像を追究する試みが進みつつあるが, 量子系についてはまだはじまったばかりである. 一成分プラズマに対して行われたいくつかのシミュレーションを振り返って, 量子シミュレーションの方法と課題を紹介し, 状態図を含めて, 得られている結果を検討する.

ソリトンとは非線形系の局在した安定な励起に与えられた名である. 従ってソリトンは基本的には等速直線運動をするもので, その集団は理想気体に近いと想像される. この想像は正しいだろうか. このような非線形系の動的現象はどのように理解されているか. セントラルピークとソリトンの関係はどうか. サイン・ゴルドン系での拡散についての最近の論争などを述べる.
