论文摘要
除了质量和西格玛介子模式的质量外，它们分解为夸克介质提供了手性伴侣的细节光谱结构。目前的文章通过使用Nambu-Jona-Lasinio模型的框架研究了手性伙伴的细节结构的有限尺寸效应。通过这种解离机制，还研究了它们的扩散和电导。手性对称性恢复相的质量，宽度，扩散系数，手性伴侣的电导率在不同的温度下合并，但是当一个人在图片中引入有限尺寸效应时，所有合并点在较低温度下都会变化。由于考虑有限的考虑，扩散和电导的强度也降低了。
Along with masses of pion and sigma meson modes, their dissociation into quark medium provide a detail spectral structures of the chiral partners. Present article has studied a finite size effect on that detail structure of chiral partners by using the framework of Nambu-Jona-Lasinio model. Through this dissociation mechanism, their diffusions and conductions are also studied. The masses, widths, diffusion coefficients, conductivities of chiral partners are merged at different temperatures in restore phase of chiral symmetry, but merging points of all are shifted in lower temperature, when one introduce finite size effect into the picture. The strengths of diffusions and conductions are also reduced due to finite size consideration.
