Reactivity of Ambident Nucleophiles in Magnetic Fields: a Combined Conceptual DFT and Current-DFT Study
Bang C. Huynh, Meilani Wibowo-Teale, Andrew M. Wibowo-Teale +2
The influence of strong external magnetic fields (up to ) on the electronic structure and reactivity of ambident nucleophiles is investigated using the nitrite and thioc…
How Semilocal Are Semilocal Density Functional Approximations? -Tackling Self-Interaction Error in One-Electron Systems
Akilan Ramasamy, Lin Hou, Jorge Vega Bazantes +4
Self-interaction error (SIE), arising from the imperfect cancellation of the spurious classical Coulomb interaction between an electron and itself, is a persistent challenge in mod…
Coupling-Constant Averaged Exchange-Correlation Hole for He, Li, Be, N, Ne Atoms from CCSD
Lin Hou, Tom J. P. Irons, Yanyong Wang +3
Accurate approximation of the exchange-correlation (XC) energy in density functional theory (DFT) calculations is essential for reliably modelling electronic systems. Many such app…
Symmetry and reactivity of -systems in electric and magnetic fields: a perspective from conceptual DFT
Meilani Wibowo-Teale, Bang C. Huynh, Andrew M. Wibowo-Teale +2
[Abridged] The extension of conceptual DFT to include external fields in chemical systems is utilised to investigate the effects of strong magnetic fields on the electronic charge…
QSym: A Quantum Symbolic Symmetry Analysis Program for Electronic Structure
Bang C. Huynh, Meilani Wibowo-Teale, Andrew M. Wibowo-Teale
Symmetry provides a powerful machinery to classify, interpret, and understand quantum-mechanical theories and results. However, most contemporary quantum chemistry packages lack th…
Magnetic Optical Rotation from Real-Time Simulations in Finite Magnetic Fields
Benedicte Sverdrup Ofstad, Meilani Wibowo-Teale, Håkon Emil Kristiansen +8
We present a numerical approach to magnetic optical rotation based on real-time time-dependent electronic-structure theory. Not relying on perturbation expansions in the magnetic-f…
