Twenty years of research have yet to produce a consensus on the origin of high-temperature
superconductivity (HTS). However, several generic characteristics of the copper oxide …

Electron—phonon coupling (EPC) in cuprate and iron-based superconducting systems, as
revealed by Raman scattering, is briefly reviewed. We introduce how to extract the coupling …

Inelastic light (Raman) scattering has been used to study electronic excitations and phonon
anomalies in detwinned, slightly overdoped YBa 2 Cu 3 O 6.95 and moderately overdoped …

The pseudogap phenomenology is one of the enigmas of the physics of high-T c
superconductors. Many members of the cuprate family have now been experimentally …

Lattice contribution to the electronic self-energy in complex correlated oxides is a fascinating
subject that has lately stimulated lively discussions. Expectations of electron-phonon self …

We performed temperature-and doping-dependent high-resolution Raman spectroscopy
experiments on YBa 2 Cu 3 O 7-δ to study B 1 g phonons. The temperature dependence of …

We report plane-polarized Raman-scattering spectra of iron oxypnictide superconductor
NdFeAsO 1− x F x single crystals with varying fluorine x content. The spectra exhibit sharp …

Understanding the origin of the pseudogap is an essential step toward elucidating the
pairing mechanism in the cuprate superconductors. Recently there has been strong …

Exploring the origin of the pseudogap is important for the understanding of superconductivity
in cuprates. Here we report a systematical experimental study on the phonon vibrational …

The iron chalcogenides have been proved to be intrinsic topological superconductors to
implement quantum computation because of their unique electronic structures. The …
