Ring-like shaped charge modulations in the t-J model with long-range Coulomb interaction
Matías Bejas, Roland Zeyher, Andrés Greco
The study of the charge excitations in cuprates is presently an interesting topic because of the development of new and precise x-ray experiments. Based on a large- formulation…
Crossover between electron-electron and electron-phonon mediated pairing on the Kagome lattice
Xianxin Wu, Debmalya Chakraborty, Andreas P. Schnyder +1
We study electron-electron and electron-phonon mediated pairing in the Holstein extended Hubbard model on the Kagome lattice near the van Hove fillings, and investigate their combi…
Plasmarons in high-temperature cuprate superconductors
Hiroyuki Yamase, Matias Bejas, Andres Greco
Metallic systems exhibit plasmons as elementary charge excitations. This fundamental concept was reinforced also in high-temperature cuprate superconductors recently, although cupr…
Low-energy plasmon excitations in infinite-layer nickelates
Luciano Zinni, Matías Bejas, Hiroyuki Yamase +1
The discovery of superconductivity in infinite-layer nickelates is presently an important topic in condensed-matter physics, and potential similarities to and differences from cupr…
Gapped collective charge excitations and interlayer hopping in cuprate superconductors
M. Hepting, M. Bejas, A. Nag +17
We use resonant inelastic x-ray scattering (RIXS) to probe the propagation of plasmons in the electron-doped cuprate superconductor SrLaCuO (SLCO). We detect a…
