具有非阿贝尔流的任意子的精确可解模型

An exactly solvable model for anyons with non-Abelian flux

Bruno Klajn, Silvije Domazet, Dario Jukić, Hrvoje Buljan

摘要:

我们提出了一个具有非阿贝尔通量的合成任意子的精确可解模型。该模型对应于一个二维的电子气在一个磁场与特定的自旋相互作用项,它只允许完全对齐的自旋状态的基态,因此基态子空间是双重简并。这个系统被带有一个非阿贝尔规范势的相同的微扰。我们探讨的基态的动力学,因为这些粒子是螺旋编织的,并显示它们的行为与非阿贝尔通量的任意子。这样的系统代表了普通阿贝尔任意子和完全非阿贝尔任意子之间的中间地带。

英文摘要:

We present an exactly solvable model for synthetic anyons carrying non-Abelian flux. The model corresponds to a two-dimensional electron gas in a magnetic field with a specific spin interaction term, which allows only fully aligned spin states in the ground state; the ground state subspace is thus two-fold degenerate. This system is perturbed with identical solenoids carrying a non-Abelian gauge potential. We explore dynamics of the ground state as these solenoids are adiabatically braided and show they behave as anyons with a non-Abelian flux. Such a system represents a middle ground between the ordinary Abelian anyons and the fully non-Abelian anyons.
