轨道对称乘积的扭曲指数理论与分数量子霍尔效应
Twisted index theory on orbifold symmetric products and the fractional quantum Hall effect
摘要:
我们扩展了非对易几何模型的分数量子霍尔效应,以前开发的Mathai和第一作者,orbifold对称产品。它保留了相同的性质量子化的霍尔电导在整数倍的分数佐竹orbifold欧拉特征。我们发现,它也允许有趣的复合费米子和任意子表示,并可能为Laughlin型波函数。
英文摘要:
We extend the noncommutative geometry model of the fractional quantum Hall effect, previously developed by Mathai and the first author, to orbifold symmetric products. It retains the same properties of quantization of the Hall conductance at integer multiples of the fractional Satake orbifold Euler characteristics. We show that it also allows for interesting composite fermions and anyon representations, and possibly for Laughlin type wave functions.
