Electron self-energy from quantum charge fluctuations in the layered t-J model with long-range Coulomb interaction
Hiroyuki Yamase, Matías Bejas, Andrés Greco
Employing a large-N scheme of the layered t-J model with the long-range Coulomb interaction, which captures fine details of the charge excitation spectra recently observed in cupra…
Detection of Acoustic Plasmons in Hole-Doped Lanthanum and Bismuth Cuprate Superconductors Using Resonant Inelastic X-Ray Scattering
Abhishek Nag, M. Zhu, Matias Bejas +11
High Tc superconductors show a rich variety of phases associated with their charge degrees of freedom. Valence charges can give rise to charge ordering or acoustic plasmons in thes…
Elastoresistance measurements on CaKFeAs and KCaFeAsF with the Fe site of symmetry
Taichi Terashima, Yoshitaka Matsushita, Hiroyuki Yamase +11
We report resistance and elastoresistance measurements on (BaK)FeAs, CaKFeAs, and KCaFeAsF. The Fe-site symmetry is in the…
Close inspection of plasmon excitations in cuprate superconductors
Andrés Greco, Hiroyuki Yamase, Matías Bejas
Recently resonant inelastic x-ray scattering experiments reported fine details of the charge excitations around the in-plane momentum for various doping…
