Hsin Lin
We have observed the bulk Fermi surface (FS) in an overdoped (x=0.3) single crystal of La₂₋ₓSrₓCuO₄ by using Compton scattering. A two-dimensional (2D) momentum density reconstruction from measured Compton profiles yields a clear FS signature in the third Brillouin zone along [100]. The quantitative agreement between density functional theory (DFT) calculations and momentum density experiment suggests that Fermi-liquid physics is restored in the overdoped regime. In particular the predicted FS topology is found to be in good accord with the corresponding experimental data. We find similar quantitative agreement between the measured 2D angular correlation of positron annihilation radiation (2D-ACAR) spectra …

Anomalous Electronic Correlations In The Ground State Momentum Density Of Al₉₇Li₃, J. Kwiatkowska, B. Barbiellini, S. Kaprzyk, A. Bansil, H. Kawata, N. Shiotani
Anomalous Electronic Correlations In The Ground State Momentum Density Of Al₉₇Li₃, J. Kwiatkowska, B. Barbiellini, S. Kaprzyk, A. Bansil, H. Kawata, N. Shiotani
Bernardo Barbiellini
We report high resolution Compton scattering measurements on an Al₉₇Li₃ disordered alloy single crystal for momentum transfer along the [100], [110] and [111] symmetry directions. The results are interpreted via corresponding KKR-CPA (Korringa-Kohn Rostoker coherent potential approximation) first principles computations. By comparing spectra for Al₉₇Li₃ and Al, we show that the momentum density in the alloy differs significantly from the predictions of the conventional Fermi liquid picture and that the ground state of Al is modified anomalously by the addition of Li.
