A Perspective on Phase Space Electronic Structure Theory : From Its Surface Hopping Origins Through To Its Future Promise
Joseph E. Subotnik, Ethan Alguire, Nicole Bellonzi +20
We trace the history of phase space electronic structure theory (PSEST), high- lighting how this powerful approach emerged from fundamental questions in semi- classical surface hop…

A Conceptual Shift In Our Understanding of Degenerate Radical Spin Systems: Spin-Rotation Coupling Turned On Its Head
Linqing Peng, Titouan Duston, Nadine Bradbury +4
For most chemists, Kramers' degeneracy refers to the fact that for any radical system, every potential energy surface is at least doubly degenerate (with spin up and spin down, tim…

Accurate crystal field Hamiltonians of single-ion magnets at mean-field cost
Linqing Peng, Shuanglong Liu, Xing Zhang +4
The effective crystal field Hamiltonian provides the key description of the electronic properties of single-ion magnets, but obtaining its parameters from ab initio computation is…
