We study a bilayer two-dimension-electron-gas (2DEG) adjacent to a type-II superconductor thin film with a pinned vortex lattice. We find that with increasing interlayer tunneling, the system of half...
Topological winding properties of spin edge states in Kane-Mele graphene model (2009)
Wang, Zhigang, Hao, Ningning, Zhang, Ping
We study the spin edge states in the quantum spin-Hall (QSH) effect on a single-atomic layer graphene ribbon system with both intrinsic and Rashba spin-orbit couplings. The Harper equation for...
Topological edge states and quantum Hall effect in the Haldane model (2008)
Hao, Ningning, Zhang, Ping, Wang, Zhigang, Zhang, Wei, Wang, Yupeng
We study the topological edge states of the Haldane's graphene model with zigzag/armchair lattice edges. The Harper equation for solving the energies of the edge states is derived. The results show...
