Reconstruction of the occupied and unoccupied electronic states driven by quantum charge fluctuations in electron doped cuprate superconductors
Hiroshi Yamaguchi, Yudai Miyai, Yuki. Tsubota +6
The origin of electron-boson interactions is central to understanding high- superconductivity in cuprates. While phonons and magnetic fluctuations are widely considered as can…

Spectroscopic Evidence for Electron-Boson Coupling in Half-metallic CrO2
Daiki Ootsuki, Hirokazu Fujiwara, Noriyuki Kataoka +9
We report quasiparticle properties of the half-metal ferromagnet CrO2 by means of high-resolution angle-resolved photoemission spectroscopy (ARPES). We clearly observed the Fermi s…
