Electron momentum densities from QSGW and : Revealing the role of many-body effects within the reduced density matrix
A. D. N. James, J. A. Gould, T. M. Mason +2
The ground-state many-body electron momentum density, which can be probed by x-ray Compton scattering, holds insights into the electronic structure of materials. Comparisons betwee…

Exposing Altermagnetism through Momentum Density Spectroscopy
Wenhan Chen, Alyn D. N. James, Stephen B. Dugdale
Materials which show a strong time-reversal symmetry-breaking response leading to spin-polarization phenomena, in conjunction with antiparallel magnetic alignments producing zero n…
