Extending orbital-optimized density functional theory to L-edge XPS and beyond: Spin-orbit coupling via non-orthogonal quasi-degenerate perturbation theory
Richard Kang, Leonardo A. Cunha, Diptarka Hait +1
Quantum mechanical calculations of core electron binding energies (CEBEs) leading to 2p hole states are relevant to interpreting L-edge x-ray photo-electron spectroscopy (XPS), as…

Relativistic Orbital Optimized Density Functional Theory for Accurate Core-Level Spectroscopy
Leonardo A. Cunha, Diptarka Hait, Richard Kang +2
Core-level spectra of 1s electrons of elements heavier than Ne show significant relativistic effects. We combine advances in orbital optimized DFT (OO-DFT) with the spin-free exact…
