涌现任意子是拓扑量子计算和拓扑量子记忆的关键元素。我们研究了一个在微调外场中具有常规两体相互作用的双分量费米子模型,并证明了在低洼激励下的几个子集遵循与环面码模型相同的融合规则。那些能量聚集在一个小空间区域(壁上)的类弦(或畴壁)激发可以被认为是准粒子,在给定的子集中,它们服从相互的符号学统计。我们展示了如何从其他简并子集中剥离一个这样的子集,并通过既定的技术在光学晶格中操纵冷偶极费米原子或冷偶极费米子异核分子中的任意子。
Emergent anyons are the key elements of the topological quantum computation and topological quantum memory. We study a two-component fermion model with conventional two-body interaction in a fine-tuned external field and show that several subsets in the low-lying excitations obey the same fusion rules as those of the toric code model. Those string-like (or domain wall) excitations whose energy congregates in a small spatial region (a wall) may be thought of as quasiparticles which, in a given subset, obey mutual semionic statistics. We show how to peel off one of such subsets from other degenerate subsets and manipulate anyons in cold dipolar Fermi atoms or cold dipolar fermionic heteronuclear molecules in optical lattices by means of the established techniques.
