论文摘要
在这项工作中，我们研究了平均野外交通事故中的$ 3+1 $二维Nambu-Jona-Lasinio（NJL）模型。我们使用五个不同的正则化方案（两个连续性和三个晶格正则化方案）进行计算，特别关注不均匀的相和冷凝水。正则化方案导致截然不同的不均匀区域。我们提供的证据表明，所有正则化方案的不均匀冷凝物几乎完全在化学势值和波数的值下，与相应的调节剂相比，波浪数的顺序或更大。这可以解释为表明$ 3+1 $维的NJL模型中的不均匀阶段是正则化的伪像，而不是NJL Lagrangian及其对称性的结果。
In this work we study the $3+1$-dimensional Nambu-Jona-Lasinio (NJL) model in the mean field-approximation. We carry out calculations using five different regularization schemes (two continuum and three lattice regularization schemes) with particular focus on inhomogeneous phases and condensates. The regularization schemes lead to drastically different inhomogeneous regions. We provide evidence that inhomogeneous condensates appear for all regularization schemes almost exclusively at values of the chemical potential and with wave numbers, which are of the order of or even larger than the corresponding regulators. This can be interpreted as indication that inhomogeneous phases in the $3+1$-dimensional NJL model are rather artifacts of the regularization and not a consequence of the NJL Lagrangian and its symmetries.
