具有非阿贝尔模和“自旋-轨道”相互作用的Abrikosov-Nielsen-Olesen弦

Abrikosov-Nielsen-Olesen string with Non-Abelian Moduli and "Spin-Orbit" Interaction

M. Shifman, A. Yung

摘要:

一般认为,庞加莱群被通量管(弦)自发破缺只会产生两个零模,这些零模局限于弦上,并与平移不变性的自发破缺有关(所谓的低马诺哈尔论证)。在许多情况下,它是完全正确的,但它是非普适的,并在序参量携带空间索引的情况下进行修改。我们表明,在某些情况下,额外的零(或准零)模式可以出现由于自旋对称性。

英文摘要:

It is generally believed that the spontaneous breaking of the Poincaré group by flux tubes (strings) generate only two zero modes localized on the string and associated with the spontaneous breaking of translational invariance (the so-called Low-Manohar argument). Being perfectly true in many instances it is nevertheless nonuniversal, and have to be amended in the case of order parameters carrying spatial indices. We show that under certain circumstances additional zero (or quasizero) modes can appear due to spin symmetry.
