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…
Theoretical perspectives on charge dynamics in high-temperature cuprate superconductors
Hiroyuki Yamase
We review recent theoretical progress on the charge dynamics of doped carriers in high-temperature cuprate superconductors. Advances in this field have clarified that doped charges…
Beyond on-site Hubbard interaction in charge dynamics of cuprate superconductors
Hiroyuki Yamase
In this review, we first present compelling evidence from resonant inelastic x-ray scattering data that highlights the significance of the long-range Coulomb interaction in cuprate…
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…
Theory of charge dynamics in bilayer electron system with long-range Coulomb interaction
Hiroyuki Yamase
We perform a comprehensive study of charge excitations in a bilayer electron system in the presence of the long-range Coulomb interaction (LRC). Our major point is to derive formul…
Impact of electron correlations on two-particle charge response in electron- and hole-doped cuprates
Abhishek Nag, Luciano Zinni, Jaewon Choi +13
Estimating many-body effects that deviate from an independent particle approach, has long been a key research interest in condensed matter physics. Layered cuprates are prototypica…
