分数量子霍尔液体中非阿贝尔准粒子统计的热电势可能探针

Thermopower as a Possible Probe of Non-Abelian Quasiparticle Statistics in Fractional Quantum Hall Liquids

Kun Yang, Bertrand I. Halperin

摘要:

本文证明了在适当的条件下,非阿贝尔量子霍尔液体的热电势是增强的。这是因为热功率在干净极限下测量每个电子的熵,而与非阿贝尔准粒子相关的简并度和熵在它们存在时增强熵。因此,热电势可以潜在地探测准粒子的非阿贝尔性质,并测量它们的量子维数。

英文摘要:

We show in this paper that thermopower is enhanced in non-Abelian quantum Hall liquids under appropriate conditions. This is because thermopower measures entropy per electron in the clean limit, while the degeneracy and entropy associated with non-Abelian quasiparticles enhance entropy when they are present. Thus thermopower can potentially probe non-Abelian nature of the quasiparticles, and measure their quantum dimension.
