Competing Interlayer Loop Currents and Superconductivity in the Bilayer -- Model
Luciano Zinni, Fabricio Gómez, Jun Zhan +4
The recent discovery of high- superconductivity in pressurized and thin-film bilayer nickelates, featuring a strong interlayer exchange coupling, and their potential similarit…
Strongly correlated model of acousticlike plasmons persisting across the phase diagram of cuprate superconductors
Luciano Zinni, Hiroyuki Yamase, Matthias Hepting +2
Layered two-dimensional electron systems exhibit both optical and acousticlike plasmons around the Brillouin-zone center. In the layered cuprate LaSrCuO, resonant i…
Strong-coupling theory of bilayer plasmon excitations
Hiroyuki Yamase, Luciano Zinni, Matías Bejas +1
Recently plasmon excitations in bilayer lattice systems were studied extensively in the weak-coupling regime. Unlike single-layer systems, these bilayers exhibit two distinct modes…
Multiorbital character of the density wave in trilayer nickelate superconductors
A. Suthar, V. Sundaramurthy, M. Bejas +15
Ruddlesden-Popper nickelates exhibit high-temperature superconductivity closely intertwined with charge and spin density waves. However, fundamental questions persist regarding the…
Retaining Landau quasiparticles in the presence of realistic charge fluctuations in cuprates
Hiroyuki Yamase, Matias Bejas, Andres Greco
Charge excitation spectra are getting clear in cuprate superconductors in momentum-energy space especially around a small momentum region, where plasmon excitations become dominant…
One-particle spectral properties of the t-J- model on the triangular lattice near charge order
M. Bejas, A. Greco, A. Muramatsu +1
We study the t-J- model beyond mean field level at finite doping on the triangular lattice. The Coulomb repulsion between nearest neighbors brings the system to a charge ord…
