Decoding Transient X-ray Absorption Spectra of Acetylacetone With Multireference Algebraic Diagrammatic Construction Theory
Bennett W. Clark, Donna H. Odhiambo, Haden Dickerson +1
Time-resolved X-ray absorption spectroscopy (TR-XAS) offers an element- and site-specific probe of coupled electronic and nuclear dynamics, but its interpretation requires methods…
Molecular g-Tensors From Spin-Orbit Quasidegenerate N-electron Valence Perturbation Theory: Benchmarks, Intruder-State Mitigation, and Practical Guidelines
Nicholas Yiching Chiang, Rajat Majumder, Alexander Yu. Sokolov
Accurate prediction of molecular g-tensors for open-shell systems requires a balanced treatment of multireference electron correlation and relativistic spin-orbit coupling. Here, w…
Core-Ionized States and X-ray Photoelectron Spectra of Solids From Periodic Algebraic Diagrammatic Construction Theory
Abdelrahman M. Ahmed, Alexander Yu. Sokolov
We present the first-ever implementation and benchmark of periodic algebraic diagrammatic construction theory (ADC) for core-ionized states and X-ray photoelectron spectra (XPS) in…
Algebraic Diagrammatic Construction Theory of Charged Excitations With Consistent Treatment of Spin-Orbit Coupling and Dynamic Correlation
