Photon echo from Maki-Thompson interference in a fluctuating s-wave superconductor
Hui Zhou, Yuan Wan
We study theoretically the nonlinear optical response of a fluctuating s-wave superconductor driven by two successive terahertz pulses. We show that the response exhibits a photon…
Theory of tunnelling into a multi-band superconductor: decoherence and interference
Da Wang, Yuan Wan, Qiang-Hua Wang
By an exact formulation of tunnelling into a multi-band superconductor in terms of Green's functions, we demonstrate that the multi-band feature of the iron-based superconductors c…
Pairing symmetry and properties of iron-based high temperature superconductors
Yuan Wan, Qiang-Hua Wang
Pairing symmetry is important to indentify the pairing mechanism. The analysis becomes particularly timely and important for the newly discovered iron-based multi-orbital supercond…
Impurity resonance states in electron-doped high T_c superconductors
Yuan Wan, Hai-Dong Lv, Hong-Yan Lu +1
Two scenarios, i.e., the anisotropic s-wave pairing (the s-wave scenario) and the d-wave pairing coexisting with antiferromagnetism (the coexisting scenario) have been introduced t…
Theory of high energy features in angle-resolved photo-emission spectra of hole-doped cuprates
Qiang-Hua Wang, Fei Tan, Yuan Wan
The recent angle-resolved photoemission measurements performed up to binding energies of the order of 1eV reveals a very robust feature: the nodal quasi-particle dispersion breaks…
