Plasmonic detection of the parity anomaly in a two-dimensional Chern insulator
M. N. Chen, Yu Zhou
In this work, we present an analytical study on the surface plasmon polaritons in a two dimensional parity anomaly Chern insulator. The connections between the topology in the bulk…
Disorder-induced phase transitions in double Weyl semimetals
Jiayan Zhang, Fei Wan, Xinru Wang +5
The double Weyl semimetal (DWSM) is a newly proposed topological material that hosts Weyl points with chiral charge n=2. The disorder effect in DWSM is investigated by adopting the…
Valley-dependent transport in strain engineering graphene heterojunctions
Fei Wan, Xinru Wang, Liehong Liao +6
We study the effect of the strain on the band structure and the valley-dependent transport property of graphene heterojunctions. It is found that valley-dependent separation of ele…
Topological hybrid semimetal phases and anomalous Hall effects in a three dimensional magnetic topological insulator
M. N. Chen, W. C. Chen, Yu Zhou
In this work, we propose a ferromagnetic BiSe as a candidate to hold the coexistence of Weyl- and nodal-line semimetal phases, which breaks the time reversal symmetry. We d…
Effect of the edge states on the conductance and thermopower in Zigzag Phosphorene Nanoribbons
R. Ma, H. Geng, W. Y. Deng +3
We numerically study the effect of the edge states on the conductance and thermopower in zigzag phosphorene nanoribbons (ZPNRs) based on the tight-binding model and the scattering-…
Non-adiabatic topological spin pumping
W. Y. Deng, W. Luo, H. Geng +3
Based on the Floquet scattering theory, we analytically investigate the topological spin pumping for an exactly solvable model. Floquet spin Chern numbers are introduced to charact…
