We consider an interface between two non-Abelian quantum Hall states: the Moore-Read state, supporting Ising anyons, and the k=2 non-Abelian spin-singlet state, supporting Fibonacci anyons. It is shown that the interface supports neutral excitations described by a (1+1)-dimensional conformal field theory with a central charge c=7/10. We discuss effects of the mismatch of the quantum statistical properties of the quasiholes between the two sides, as reflected by the interface theory.
支持伊辛任意子的摩尔 - 里德态,以及支持斐波那契任意子的(k = 2)非阿贝尔自旋单态。结果表明,该界面支持由中心荷(c = 7/10)的((1 + 1))维共形场论描述的中性激发。我们讨论了界面理论所反映的两侧准空穴量子统计性质不匹配的影响。
