大几何相位与非基本单极子

Large geometric phases and non-elementary monopoles

Patricio Leboeuf, Amaury Mouchet

摘要:

简并在光谱中的一个磁输运量子系统是重要的,以确定几何相位因子,并可以解释为磁单极子。我们调查的机制,约束作用于系统,有关的局部对称性,可以创建任意大的电荷。这些电荷与简并度的不同几何形状有关。给出了计算电荷的显式方法和几个实例。

英文摘要:

Degeneracies in the spectrum of an adiabatically transported quantum system are important to determine the geometrical phase factor, and may be interpreted as magnetic monopoles. We investigate the mechanism by which constraints acting on the system, related to local symmetries, can create arbitrarily large monopole charges. These charges are associated with different geometries of the degeneracy. An explicit method to compute the charge as well as several illustrative examples are given.
