Softening of excitation in the resonant inelastic x-ray scattering spectra as a signature of Hund's coupling in nickelates
Umesh Kumar, Corey Melnick, Gabriel Kotliar
We investigate the effects of Hund's coupling on the resonant X-ray absorption spectra of the recently discovered family of layered nickelate superconductors. We contrast two scena…
ComDMFT v.2.0: Fully Self-Consistent ab initio GW+EDMFT for the Electronic Structure of Correlated Quantum Materials
Byungkyun Kang, Patrick Semon, Corey Melnick +5
ComDMFT is a parallel computational package designed to study the electronic structure of correlated quantum materials from first principles. Our approach is based on the combinati…
Accuracy of ghost-rotationally-invariant slave-boson theory for multiorbital Hubbard models and realistic materials
Tsung-Han Lee, Corey Melnick, Ran Adler +2
We assess the accuracy of the ghost-rotationally-invariant slave-boson (g-RISB) theory in multiorbital systems by applying it to both the three-orbital degenerate Hubbard model and…
