用突变理论解质子-中子相互作用玻色子模型中的相变和临界点

Disentangling phase transitions and critical points in the proton-neutron interacting boson model by catastrophe theory

J. E. Garcia-Ramos, J. M. Arias, J. Dukelsky

摘要:

我们介绍了突变理论的基本概念,需要得到解析的质子-中子相互作用玻色子模型(IBM-2)的相图。以前的研究[1,2,3]是基于数值解。在这里,我们解释了整个IBM-2相图,包括在尖点突变方面的相变的精确顺序。

英文摘要:

We introduce the basic concepts of catastrophe theory needed to derive analytically the phase diagram of the proton-neutron interacting boson model (IBM-2). Previous studies [1,2,3] were based on numerical solutions. We here explain the whole IBM-2 phase diagram including the precise order of the phase transitions in terms of the cusp catastrophe.
