Charge excitations in LiV $_{2}$ O $_{5}$ and NaV $_{2}$ O $_{5}$ : similarities and differences

A. Huebsch, C. Waidacher, K. W. Becker

We calculate the optical conductivity of LiV $_{2}$ O $_{5}$ and NaV $_{2}$ O $_{5}$ using exact numerical diagonalization of a quarter-filled extended Hubbard model on a system of coupl…

Charge excitations in NaV $_{2}$ O $_{5}$

A. Huebsch, C. Waidacher, K. W. Becker +1

We calculate the electron-energy loss spectrum and the optical conductivity for NaV $_{2}$ O $_{5}$ using the standard Lanczos algorithm. The vanadium ions in NaV $_{2}$ O $_{5}$ form a…

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…
