论文摘要
在两种味道的Nambu-Jona-Lasinio模型的背景下，我们研究了有限大小和热磁性对夸克物质的特性的组合作用。特别是，通过使用周期性或反碘条件的环形拓扑结构使用平均场近似和适当的时间方法，我们评估了手性相变，组成夸克质量以及在外部磁场的大小，温度和强度的变化下的热和空间敏感性。考虑到反磁催化现象，我们使用了最近提出的磁化耦合常数。研究结果表明，可观察物受到变量变化以及边界条件的周期性的强烈影响，并取决于这些竞争现象的平衡。
We investigate the combined finite-size and thermo-magnetic effects on the properties of the quark matter, in the context of the two-flavored Nambu--Jona-Lasinio model. In particular, by using the mean-field approximation and the Schwinger proper time method in a toroidal topology with periodic or antiperiodic conditions, we evaluate the chiral phase transition, the constituent quark mass and the thermal and spatial susceptibilities under the change of the size, temperature and strength of external magnetic field. To take into account the inverse magnetic catalysis phenomenon, we make use of a recently proposed magnetized coupling constant. The findings suggest that the observables are strongly affected by the variation of the variables and also by the periodicity of the boundary conditions, with the final outcomes depending on the balance of these competing phenomena.
