剧烈核反应：费米子系统中的大振幅核动力学现象
Violent Nuclear Reactions: Large-Amplitude Nuclear Dynamic Phenomena in Fermionic Systems
摘要：
剧烈的核碰撞是开放的系统，需要一个非平衡态的描述时，该过程应遵循从第一时刻。在碰撞中产生的加热系统，不能再处理在一个独立的粒子图片和额外的相关性应考虑在内：他们依赖于介质中的耗散和相空间的波动。它们与单体集体行为的相互作用激活了传输动力学：出现了各种机制的大幅波动和分叉，从融合到颈部形成，直到最终将系统冻结成几个中等质量的集群。从核物质测试的基本概念出发，建立了一个微观描述，以解决发生在重离子碰撞在费米能量和spiral反应的暴力过程，它被应用到实验观测。
英文摘要：
Violent nuclear collisions are open systems which require a non-equilibrium description when the process should be followed from the first instants. The heated system produced in the collision, can no more be treated within an independent-particle picture and additional correlations should be taken into account: they rely to in-medium dissipation and phase-space fluctuations. Their interplay with the one-body collective behaviour activates the transport dynamics: large-amplitude fluctuations and bifurcations in a variety of mechanisms appear, from fusion to neck formation till eventually freezing out the system into several intermediate-mass clusters. Starting from fundamental concepts tested on nuclear matter, a microscopic description is built up to address violent processes occurring in heavy-ion collisions at Fermi energies and in spallation reactions, and it is applied to experimental observables.
