Quantum many-body effects in x-ray spectra efficiently computed using a basic graph algorithm
Quantum many-body effects in x-ray spectra efficiently computed using a basic graph algorithm
The growing interest in using x-ray spectroscopy for refined materials characterization calls for accurate electronic-structure theory to interpret x-ray near-edge fine structure. In this work, we propose an efficient and unified framework to describe all the many-electron processes in a Fermi liquid after a sudden perturbation (such as a core …
