夸克胶子等离子体（QGP）是强相互作用物质的解禁闭相，它曾经存在于早期的宇宙，也有可能存在于中子星内部。高能核核碰撞可以在瞬间产生QGP所需要的极端条件，揭示高温高密下强相互作用物质的相变和性质，并帮助人们近一步认识宇宙极早期的演化。在传统的相对论重离子碰撞中（例如200 A GeV的Au-Au碰撞），强耦合的夸克胶子等离子体QGP已经产生并被发现，其存在的三个重要的证据为：强的集体流，椭圆流的价...

We study whether the neutron skin thickness $\Delta r_{np}$ of ${}^{208}$Pb originates from the bulk or from the surface of the neutron and proton density distributions in mean field models.
