Raman spectra of fine-grained materials from first principles
Maxim N. Popov, Jürgen Spitaler, Vignaswaran K. Veerapandiyan +3
Raman spectroscopy is an advantageous method for studying the local structure of materials, but the interpretation of measured spectra is complicated by the presence of oblique pho…

Optical properties and Raman scattering of vanadium ladder compounds
J. Spitaler, E. Ya. Sherman, C. Ambrosch-Draxl +1
We investigate electronic and optical properties of the V-based ladder compounds NaV2O5, the iso-structural CaV2O5, as well as MgV2O5, which differs from NaV2O5 and CaV2O5 in the c…

Charge ordering in quarter-filled ladder systems coupled to the lattice
M. Aichhorn, M. Hohenadler, E. Ya. Sherman +3
We investigate charge ordering in the presence of electron-phonon coupling for quarter-filled ladder systems by using Exact Diagonalization. As an example we consider NaV2O5 using…
