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, MatÃas 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…

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…
