Realistic description of electron-energy loss spectroscopy for One-Dimensional SrCuO
A. Huebsch, J. Richter, C. Waidacher +2
We investigate the electron-energy loss spectrum of one-dimensional undoped CuO chains within an extended multi-band Hubbard model and an extended one-band Hubbard model, usi…
The dynamics of a hole in a CuO_4 plaquette: electron energy-loss spectroscopy of Li_2CuO_2
S. Atzkern, M. Knupfer, M. S. Golden +7
We have measured the energy and momentum dependent loss function of Li_2CuO_2 single crystals by means of electron energy-loss spectroscopy in transmission. Using the same values f…
Cu-O network dependent core-hole screening in low-dimensional cuprates: A theoretical analysis
C. Waidacher, J. Richter, K. W. Becker
We analyze the influence of the dimensionality on the Cu 2p_3/2 core level X-ray photoemission spectra of undoped cuprates. Both exchange splitting and delocalization properties ar…
The role of Zhang-Rice singlet-like excitations in one-dimensional cuprates
J. Richter, C. Waidacher, K. W. Becker
We present the first calculation of the electron-energy loss spectrum of infinite one-dimensional undoped CuO_3 chains within a multi-band Hubbard model. The results show good agre…
