动量空间中的一级相变及其展开

First-order Phase Transition and Resulted Expansion in Momentum Space

Feng Li

摘要:

根据熵增长原理,指出在一级相变过程中,系统在动量空间中所占的体积应扩大。通过基于NJL型拉格朗日量的输运模型的模拟,这种膨胀被可视化,并被几个观测量量化,其中一些观测量是本文首次提出的,它们可能是发生在重离子碰撞中夸克-胶子等离子体和强子相之间的一级相变或其他膨胀系统的探针.

英文摘要:

We point out, according to the principle of entropy growth, that the volume occupied by the system in the momentum space should expand during the first-order phase transition. Such an expansion is visualized by the simulation using the transport model based on a NJL-typed Lagrangian, and quantified by several observables, some of which, proposed for the first time in this article, could be the probes of the first-order phase transition either between the quark gluon plasma and the hadronic phase taking place in the heavy-ion collisions or of the other expanding systems.
