对称相互作用Kitaev链零模的显式形式

Explicit forms of zero modes in symmetric interacting Kitaev chain without and with dimerization

Yiming Wang, Zhidan Li, Qiang Han

摘要:

揭示了一维相互作用Kitaev链在对称点处的费米零模和玻色子零模。通过无限阶微扰展开,给出了拓扑区域中Majorana零模的多体结构。给出了拓扑平凡相中玻色子零模的解析表达式。我们的结果被推广到由相互作用Kitaev模型和Su-Schrieffer-Heeger模型组成的混合费米子系统,证明了这两种零模可以共存于相图的某个区域.

英文摘要:

The fermionic and bosonic zero modes of the 1D interacting Kitaev chain at the symmetric point are unveiled. The many-body structures of the Majorana zero modes in the topological region are given explicitly by carrying out perturbation expansion up to infinite order. We also give the analytic expressions of the bosonic zero modes in the topologically trivial phase. Our results are generalized to the hybrid fermion system comprised of the interacting Kitaev model and the Su-Schrieffer-Heeger model, in which we show that these two types of zero modes can coexist in certain region of its phase diagram.
