Topological superconductivity in a topological insulator
Hao Yu, Noah F. Q. Yuan, Wei-Jian Li +6
Topological superconductivity is an exotic quantum phenomenon with coupled nontrivial topological order and superconductivity together. A direct idea for producing topological supe…
Resonance, Fermi surface topology, and Superconductivity in Cuprates
Yuan Zhou, Haiyang Zhang, Haiqing Lin +1
The resonance, a collective boson mode, was usually thought to be a possible glue of superconductivity. We argue that it is rather a natural product of the \emph{d}-wave pairing an…
Superconducting Resonance and paring symmetry in electron-doped cuprates
H. Y. Zhang, Y. Zhou, C. D. Gong +1
The magnetic excitations in the superconducting electron-doped cuprates are studied in the framework of spin-density-wave description. The superconducting resonance is a natural pr…
Tunable striped-patterns by lattice anisotropy and magnetic impurities in d-wave superconductors
Xian-Jun Zuo, Yuan Zhou, Chang-De Gong
The pattern transition induced by lattice anisotropy (LA) and magnetic impurities is computationally observed in near-optimally doped d-wave superconductors (DSCs). For the single…
Local enhancement of spin and orbital antiferromagnetism around a single vortex in high-Tc superconductors
Jin An, Chang-De Gong
In a simple model we investigate three competing orders: d-wave superconductivity, spin and orbital antiferromagnetism (AF) in the vicinity of a single vortex in a cuprate supercon…
Doping dependence of the resonance peak and incommensuration in high- superconductors
Jian-Xin Li, Chang-De Gong
The doping and frequency evolutions of the incommensurate spin response and the resonance mode are studied based on the scenario of the Fermi surface topology. We use the slave-bos…
Superconducting condensation energy and neutron resonance in high-Tc superconductors
Jian-Xin Li, Chung-Yu Mou, Chang-De Gong +1
Based on the slave-boson theory of the two-dimensional model, we calculate the superconducting condensation energy for optimally doped and overdoped high cuprates…
Impurity effects on the spin excitation spectra in a d-wave superconductor
Jian-Xin Li, Wei-Guo Yin, Chang-De Gong
The effects of nonmagnetic impurity on the spin excitation spectra in a -wave superconductor are examined, using the self-consistent -matrix approximation. It is sh…
