袋状模型中的交叉跃迁
Crossover transition in bag-like models
摘要：
我们制定了一个简单的模型，在零化学势的扩展强子气体的灵感来自可压缩袋模型。我们证明了通过引入适当的附加动力学，这种系统可以再现与格点量子色动力学性质相似的交叉跃迁。在一定条件下，在高温下，系统由有限数量的无限延伸的袋组成，这些袋占据了整个空间。在这种情况下，系统表现为一种由夸克和胶子组成的理想气体。
英文摘要：
We formulate a simple model for a gas of extended hadrons at zero chemical potential by taking inspiration from the compressible bag model. We show that a crossover transition qualitatively similar to lattice QCD can be reproduced by such a system by including some appropriate additional dynamics. Under certain conditions, at high temperature, the system consist of a finite number of infinitely extended bags, which occupy the entire space. In this situation the system behaves as an ideal gas of quarks and gluons.
