Quantum interference in dirty d-wave superconductors
Hong-Yi Chen, Lingyin Zhu, C. S Ting
The local differential tunneling conductance on a Zn impurity in a disordered d-wave superconductors is studied. Quantum interference between many impurities leads to definitive qu…
The temperature dependence of the local tunnelling conductance in cuprate superconductors with competing AF order
Hong-Yi Chen, C. S. Ting
Based on the model with proper chosen parameters for describing the cuprate superconductors, it is found that near the optimal doping at low temperature (), only the…
LDOS modulations in cuprate superconductors with competing AF order: the temperature effect
Hong-Yi Chen, C. S. Ting
Based upon a phenomenological model and using Bogoliubov-de Gennes equations, we found that near the optimal doping at low temperature (), only the pure d-wa…
Spatial Distribution of LDOS in Cuprate Superconductors With Magnetic-Field-Induced Stripe Modulation
Hong-Yi Chen, C. S. Ting
A phenomenological model defined in a two dimensional lattice is employed to investigate the d-wave superconductivity and the competing antiferromagnetic order in cuprate supercond…
Impurity effects on s+g-wave superconductivity in borocarbides Y(Lu)Ni_2B_2C
Qingshan Yuan, Hong-Yi Chen, H. Won +4
Recently a hybrid s+g-wave pairing is proposed to describe the experimental observation for a nodal structure of the superconducting gap in borocarbide YNiBC and possibly L…
Local Density of States in a d-wave Superconductor with Stripe-Like Modulations and a Strong Impurity
Hong-Yi Chen, C. S. Ting
Using an effective Hamiltonian with d-wave superconductivity (dSC) and competing antiferromagnetic (AF) interactions, we show that weak and one-dimensionally modulated dSC, spin de…
