量子霍尔液滴的手征配分函数

Chiral Partition Functions of Quantum Hall Droplets

A. Cappelli, G. Viola, G. R. Zemba

摘要:

共形场论的手征配分函数描述了孤立霍尔液滴的边缘激发。它们的特点是由一个指数指定准粒子部门和变换之间的有限维表示的模群。推导了配分函数,并用于描述导致库仑阻塞电导峰的电子跃迁。我们发现了阿贝尔层次态和非阿贝尔Read-Rezayi态的峰值模式,并对它们进行了比较。对这些特征的实验观察可以检验共形场论描述的定性性质,例如希尔伯特空间分成扇区的分解,包括带电和中性部分,以及融合规则。

英文摘要:

Chiral partition functions of conformal field theory describe the edge excitations of isolated Hall droplets. They are characterized by an index specifying the quasiparticle sector and transform among themselves by a finite-dimensional representation of the modular group. The partition functions are derived and used to describe electron transitions leading to Coulomb blockade conductance peaks. We find the peak patterns for Abelian hierarchical states and non-Abelian Read-Rezayi states, and compare them. Experimental observation of these features can check the qualitative properties of the conformal field theory description, such as the decomposition of the Hilbert space into sectors, involving charged and neutral parts, and the fusion rules.
