Impurity states in antiferromagnetic Iron Arsenides
Q. Han, Z. D. Wang
We explore theoretically impurity states in the antiferromagnetic spin-density wave state of the iron arsenide. Two types of impurity models are employed: one has only the intraban…
A Generic Two-band Model for Unconventional Superconductivity and Spin-Density-Wave Order in Electron and Hole Doped Iron-Based Superconductors
Q. Han, Y. Chen, Z. D. Wang
Based on experimental data on the newly synthesized iron-based superconductors and the relevant band structure calculations, we propose a minimal two-band BCS-type Hamiltonian with…
Nuclear Spin Relaxation Rate of Disordered -wave Superconductors
Q. Han, Z. D. Wang
Based on an effective Hamiltonian with the binary alloy disorder model defined in the triangular lattice, the impurity scattering effects on the density of states and especially on…
Vortex State in Na_xCoO_2.yH_2O: p_x\pm ip_y-wave versus d_{x^2-y^2}\pm id_{xy}-wave Pairing
Qiang Han, Z. D. Wang, Q. -H. Wang +1
Based on an effective Hamiltonian specified in the triangular lattice with possible - or -wave pairing, which has close relevance to the newly…
