非超对称香料的动力学
Dynamics of Non-supersymmetric Flavours
摘要:
本文研究了Kuperstein-Sonnenschein模型中非超对称探针的反反应效应。在逆反应小的极限下,讨论了逆反应几何的物理性质。我们进一步介绍了额外的探针味道在这个反反应的几何形状和详细研究的相位结构时,这个部门的一个恒定的电磁场或化学势存在。我们发现,朗道极点,这是作为背景几何的UV截止,也作为一个重要的规模在相应的热力学的附加风味部门。我们注意到,由于这些额外的探针的味道是无法区分的反反应的味道,我们得到的结果指向一个更丰富的相结构的系统。
英文摘要:
We investigate the effect of the back-reaction by non-supersymmetric probes in the Kuperstein-Sonnenschein model. In the limit where the back-reaction is small, we discuss physical properties of the back-reacted geometry. We further introduce additional probe flavours in this back-reacted geometry and study in detail the phase structure of this sector when a constant electromagnetic field or a chemical potential are present. We find that the Landau pole, which serves as the UV cut-off of the background geometry, also serves as an important scale in the corresponding thermodynamics of the additional flavour sector. We note that since these additional probe flavours are indistinguishable from the back-reacting flavours, the results we obtain point to a much richer phase structure of the system.
