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…
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…
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…
Phase Space Electronic Structure Theory: From Diatomic Lambda-Doubling to Macroscopic Einstein-de Haas
Linqing Peng, Tian Qiu, Nadine Bradbury +5
-doubling of diatomic molecules is a subtle microscopic phenomenon that has long attracted the attention of experimental groups, insofar as rotation of molecular $\textit{nucle…
Non-Resonant Raman Optical Activity From Phase-Space Electronic Structure Theory
Zhen Tao, Mansi Bhati, Joseph E. Subotnik
In order to model experimental non-resonant Raman optical activity, chemists must compute a host of second-order response tensors, (e.g. the electric-dipole magnetic-dipole polariz…
The Phase-Space Way To Electronic Structure Theory and Subsequently Chemical Dynamics
Xuezhi Bian, Titouan Duston, Nadine Bradbury +6
Phase-space electronic structure theory offers up a new and powerful approach for tackling problems with coupled nuclear-electronic dynamics in a fashion that goes beyond Born-Oppe…
