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…
Symmetry and Topology in Wavepacket Dynamics near Conical Intersections
Christopher Daggett, Jonathan Rawlinson, Lukas Muechler
Whether topology directly shapes chemical dynamics remains an open question in theoretical chemistry. The issue arises because degeneracies of adiabatic electronic states can gener…
Recovering Exact Vibrational Energies Within a Phase Space Electronic Structure Framework
Xinchun Wu, Xuezhi Bian, Jonathan Rawlinson +2
In recent years, there has been a push to go beyond Born-Oppenheimer theory and build electronic states from a phase space perspective, i.e. parameterize electronic states by both…
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…
A Phase-Space Electronic Hamiltonian for Molecules in a Static Magnetic Field II: Quantum Chemistry Calculations with Gauge Invariant Atomic Orbitals
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…
