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…
Optical and acoustic plasmons in the layered material SrRuO
J. Schultz, A. Lubk, F. Jerzembeck +5
We use momentum-dependent electron energy-loss spectroscopy in transmission to study collective charge excitations in the layer metal SrRuO. This metal has a transition fro…
Linear plasmon dispersion in single-wall carbon nanotubes and the collective excitation spectrum of graphene
C. Kramberger, R. Hambach, C. Giorgetti +12
We have measured a strictly linear pi-plasmon dispersion along the axis of individualized single wall carbon nanotubes, which is completely different from plasmon dispersions of gr…
Cu-O network dependent core hole screening in low-dimensional cuprate systems: a high-resolution x-ray photoemission study
T. Böske, K. Maiti, O. Knauff +8
We present an experimental study of the dynamics of holes in the valence bands of 0, 1, and 2 dimensional undoped model cuprates, as expressed via the screening of a Cu 2p core hol…
