Topological properties of the dimerized Kitaev chain with long-range hopping and pairing terms
Xue-Si Li, Jia-Rui Li, Shu-Feng Zhang +2
We investigate the topological properties of a dimerized Kitaev chain with long-range interactions, including the intercell hopping and superconducting pairing terms. It is found t…

symmetry of the Su-Schrieffer-Heeger model with imaginary boundary potentials and next-nearest-neighboring coupling
Xue-Si Li, Ze-Zhong Li, Lian-Lian Zhang +1
By introducing the next-nearest-neighboring (NNN) intersite coupling, we investigate the eigenenergies of the -symmetric non-Hermitian Su-Schrieffer-Heeger (SSH) model wit…

Double Andreev reflections and double electron transmissions in a normal-superconductor-normal junction based on type-II Weyl semimetal
Xue-Si Li, Shu-Feng Zhang, Xue-Rui Sun +1
We study the quantum transport behavior of a normal-superconductor-normal junction based on type-II Weyl semimetal, which is arranged in the tilting direction of the Weyl semimetal…
