具有负通量的非阿贝尔态:一系列新的量子Hall态

Non-Abelian states with negative flux: a new series of quantum Hall states

Thierry Jolicoeur

摘要:

将仿费米子成团的思想应用于具有正负通量的复合玻色子,提出了一系列新的描述分数量子霍尔态的试探波函数。这些非阿贝尔态与其他基态如条纹或复合费米子态竞争填充因子k/(3 k +/- 2)。这两个系列包含了潘等人最近发现的所有状态。90,016801(2003)],包括偶数分母情况。精确对角化的研究领域和环面点,他们可能的相关性填充因子3/7,3/11和3/8。

英文摘要:

By applying the idea of parafermionic clustering to composite bosons with positive as well as negative flux, a new series of trial wavefunctions to describe fractional quantum Hall states is proposed. These non-Abelian states compete at filling factors k/(3k +/- 2) with other ground states like stripes or composite fermion states. These two series contain all the states recently discovered by Pan et al. [Phys. Rev. Lett. 90, 016801 (2003)] including the even denominator cases. Exact diagonalization studies on the sphere and torus point to their possible relevance for filling factors 3/7, 3/11, and 3/8.
