Topological properties in the non-Hermitian tetramerized Su-Schrieffer-Heeger lattices
Jia-Rui Li, Lian-Lian Zhang, Wei-Bin Cui +1
In this paper, we study the topological properties of the non-Hermitian Su-Schrieffer-Heeger (SSH) lattice by periodically introducing onsite imaginary potentials in the manner of…
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…
Erasable signature of Majorana bound state due to coupling with the T-shaped quantum-dot structure
Wei-Jiang Gong, Yu-Hang Xue, Xiao-Qi Wang +2
We theoretically study the transport properties in the T-shaped double-quantum-dot structure, by introducing the Majorana bound state (MBS) to couple to the dot in the main channel…
Manipulability of the Kondo effect in a T-shaped triple-quantum-dot structure
Guang-Yu Yi, Cui Jiang, Lian-Lian Zhang +3
We theoretically investigate the Kondo effect of a T-shaped triple-quantum-dot structure, by means of the numerical renormalization group method. It is found that at the point of e…
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…
Transport properties in a Non-Hermitian triple-quantum-dot structure
Lian-Lian Zhang, Wei-Jiang Gong
In this work, we study the effect of -symmetric complex potentials on the transport properties of one non-Hermitian system, which is formed by the coupling between a…
