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 Phase Space Electronic Structure View of The Solid State
Nadine Bradbury, Joseph Subotnik
We develop a phase space electronic structure view of the solid state, where electronic bands are parameterized by both nuclear position and nuclear momentum $\mathbfΠ…
Electronic Structure in a Phase Space, non-Born-Oppenheimer Framework: Geometric Forces and Moody-Shapere-Wilzcek Revisited
Mansi Bhati, D. Vale Cofer-Shabica, Jonathan I. Rawlinson +3
The paper introduces a phase‑space electronic‑structure framework that extends the Born‑Oppenheimer approximation by treating electronic states as functions of both nuclear positio…
Electron Transfer, Diabatic Couplings and Vibronic Energy Gaps in a Phase Space Electronic Structure Framework
Zain Zaidi, Xuezhi Bian, Joseph E. Subotnik
We investigate the well-known Shin-Metiu model for an electronic crossing, using both a standard Born-Huang (BH) framework and a novel phase space (PS) electronic Hamiltonian frame…
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…
Charge Transfer with a Spin. II: A Framework for Diabatization which Localizes Charge and Spin
Alok Kumar, Zhen Tao, Zuxin Jin +2
We investigate a diabatization procedure that localizes charges (in real space) and localizes spins (in spin space) for open-shell systems that exhibit charge transfer in the prese…
