Proposal to determine the Fermi-surface topology of a doped iron-based superconductor using bulk-sensitive Fourier-transform Compton scattering
Yung Jui Wang, Hsin Lin, B. Barbiellini +4
We have carried out first-principles calculations of the Compton scattering spectra to demonstrate that the filling of the hole Fermi surface in LaOFFeAs produces a d…
High resolution Compton scattering as a Probe of the Fermi surface in the Iron-based superconductor
Y. J. Wang, Hsin Lin, B. Barbiellini +5
We have carried out first principles all-electron calculations of the (001)-projected 2D electron momentum density and the directional Compton profiles along the [100], [001] and […
Treatment of Correlation Effects in Electron Momentum Density: Density Fuctional Theory and Beyond
B. Barbiellini, A. Bansil
Recent high resolution Compton scattering experiments clearly reveal that there are fundamental limitations to the conventional local density approximation (LDA) based description…
A natural orbital method for the electron momentum distribution in matter
B. Barbiellini
A variational method for many electron system is applied to momentum distribution calculations. The method uses a generating two-electron geminal and the amplitudes of the occupanc…
