论文摘要
我们重新考虑了1+1个维度的大型手性毛发模型的两种味道版本。它的相图是Baryon化学潜力的函数,Isospin化学势和温度先前已被探索。我们概括了结果,并添加了缺少的三斜曲线。可以通过使用第四阶几乎退化的扰动理论来确切确定它们通过扩展标准稳定性分析。提出和讨论了三种不同裸露质量的结果。
We reconsider the two-flavor version of the massive, chiral Gross-Neveu model in 1+1 dimensions. Its phase diagram as a function of baryon chemical potential, isospin chemical potential and temperature has previously been explored. We recapitulate the results, adding the missing tricritical curves. They can be determined exactly by extending the standard stability analysis, using fourth order almost degenerate perturbation theory. Results for three different bare masses are presented and discussed.
