1+1 Gross Neveu模型的Ginzburg-Landau型逼近--超越最低非平凡阶

Ginzburg-Landau Type Approach to the 1+1 Gross Neveu Model - Beyond Lowest Non-Trivial Order

Anees Ahmed

摘要:

本文以1+1维Gross-Neveu模型为例,研究了增加Ginzburg-Landau型展开式的阶数对系统性能的影响.据发现,作为扩展的顺序增加,预测的相图越来越类似于已知的确切的相图。最后,研究了任意高阶相图的一些性质。

英文摘要:

This paper presents a case study of the effects of increasing the order of a Ginzburg-Landau type expansion, by using the well known Gross-Neveu model in 1+1 dimensions as a test case. It is found that as the order of expansion increases, the predicted phase diagram increasingly resembles the known exact phase diagram. Finally, some properties of arbitrary large order phase diagrams are examined.
