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…
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…
Charge Transfer with a Spin. I: A Variational Constrained-CASSCF Framework for Investigating Charge Transfer in the Presence of Spin-Orbit Coupling
Alok Kumar, Zhen Tao, Joseph E. Subotnik +1
Charge transfer in open-shell molecular systems can involve a delicate interplay between charge localization, orbital relaxation, and spin-orbit coupling (SOC), particularly near g…
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…
Conical Intersections and Electronic Momentum As Viewed From Phase Space Electronic Structure Theory
Titouan Duston, Nadine Bradbury, Zhen Tao +1
We investigate the structure of a prototypical two-state conical intersection (BeH) using a phase space electronic Hamiltonian $\hat{H}_{PS}(\bR,\bP)$ that goes beyond the Born…
Symmetry Breaking as Predicted by a Phase Space Hamiltonian with a Spin Coriolis Potential
Nadine C. Bradbury, Titouan Duston, Zhen Tao +3
We perform electronic structure calculations for a set of molecules with degenerate spin-dependent ground states (CH, CH, O) going beyond the Born…

Mansi Bhati, Zhen Tao, Xuezhi Bian +3
In a companion paper, we have developed a phase-space electronic structure theory of molecules in magnetic fields, whereby the electronic energy levels arise from diagonalizing a p…
A Phase-Space Electronic Hamiltonian for Molecules in a Static Magnetic Field I: Conservation of Total Pseudomomentum and Angular Momentum
Mansi Bhati, Zhen Tao, Xuezhi Bian +3
We develop a phase-space electronic structure theory of molecules in magnetic fields. For a system of electrons in a magnetic field with vector potential , th…
A Basis-Free Phase Space Electronic Hamiltonian That Recovers Beyond Born-Oppenheimer Electronic Momentum and Current Density
Zhen Tao, Tian Qiu, Xuezhi Bian +1
We present a phase-space electronic Hamiltonian (parameterized by both nuclear position and momentum ) that boosts each electron into the mo…
Practical Phase-Space Electronic Hamiltonians for Ab Initio Dynamics
Zhen Tao, Tian Qiu, Mansi Bhati +5
Modern electronic structure theory is built around the Born-Oppenheimer approximation and the construction of an electronic Hamiltonian H_{el}(X) that depends on the nuclear positi…
Total Angular Momentum Conservation in Ehrenfest Dynamics with a Truncated Basis of Adiabatic States
Zhen Tao, Xuezhi Bian, Yanze Wu +3
We show that standard Ehrenfest dynamics does not conserve linear and angular momentum when using a basis of truncated adiabatic states. However, we also show that previously propo…
