Through a Lattice Darkly: Shedding Light on Electron-Phonon Coupling in the High Tc Cuprates

Autor: D. R. Garcia, A. Lanzara

Publikováno v: Advances in Condensed Matter Physics, Vol 2010 (2010)

With its central role in conventional BCS superconductivity, electron-phonon coupling appears to play a more subtle role in the phase diagram of the high-temperature superconducting cuprates. Their added complexity due to potentially numerous competi

With the current interest in the rare-earth tellurides as high temperature charge density wave materials, a greater understanding of the physics of these systems is needed, particularly in the case of the ditellurides. We report a detailed study of t

We have studied ${\text{Bi}}_{2}{\text{Sr}}_{1.6}{\text{Nd}}_{0.4}{\text{CuO}}_{6+\ensuremath{\delta}}$ using angle-resolved photoemission spectroscopy in the optimal and overdoped regions of the phase diagram. We identify a narrow crossover region i

We report the first measurement of the Cu-O bond stretching phonon dispersion in optimally doped Bi2Sr1.6La0.4Cu2O6+delta using inelastic x-ray scattering. We found a softening of this phonon at q=(0.25,0,0) from 76 to 60 meV, similar to the one repo

We present the first direct study of charge density wave (CDW) formation in quasi-2D single layer LaTe_2 using high-resolution angle resolved photoemission spectroscopy (ARPES) and low energy electron diffraction (LEED). CDW formation is driven by Fe
