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…
