定量计算了Gross-Neveu模型的相图与重整化温度和化学势的关系。在有限温度和化学势为零的条件下，发现了一条从已知的二阶手征对称性恢复跃迁开始的跃迁线。它在图的内部将其性质变为一级，并继续到化学势轴。
The phase diagram of the Gross-Neveu model as a function of renormalized temperature and chemical potential is worked out quantitatively. A line of transitions is found, that starts at the known second-order chiral symmetry restoration transition at finite temperature and vanishing chemical potential. It changes its character to first order in the interior of the diagram and continues to the chemical potential axis.
