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…
A semiclassical non-adiabatic phase-space approach to molecular translations and rotations: A new picture of surface hopping and electronic inertial effects
Xuezhi Bian, Yanze Wu, Tian Qiu +2
We present a novel semiclassical phase-space surface hopping approach that goes beyond the Born-Oppenheimer approximation and all existing surface hopping formalisms. We demonstrat…
An Efficient Algorithm for Constrained CASSCF(1,2) and CASSCF(3,2) Simulations as Relevant to Electron and Hole Transfer Problems
Tian Qiu, Joseph E. Subotnik
We propose an efficient algorithm for the recently published electron/hole-transfer Dynamical-weighted State-averaged Constrained CASSCF (eDSC/hDSC) method studying charge transfer…
Can The Mystery of The Born-Oppenheimer Electronic Current Density Be Explained With A Simple Phase Space Electronic Hamiltonian? Yes (And A Lot More Too)
Zhen Tao, Titouan Duston, Zheng Pei +4
We show that a phase space electronic Hamiltonian , parameterized by both nuclear position and momentum , can recover…
A phase-space view of vibrational energies without the Born-Oppenheimer framework
Xuezhi Bian, Cameron Khan, Titouan Duston +3
We show that following the standard mantra of quantum chemistry and diagonalizing the Born-Oppenheimer (BO) Hamiltonian is not the optimal means to constru…
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…
A Phase Space Approach to Vibrational Circular Dichroism
Titouan Duston, Zhen Tao, Xuezhi Bian +6
We show empirically that a phase-space non-Born-Oppenheimer electronic Hamiltonian approach to quantum chemistry (where the electronic Hamiltonian is parameterized by both nuclear…
Spin-Dependent Stereochemistry: A Non-adiabatic Quantum Dynamics Case Study of S + H2 -> SH + H Reaction
Xuezhi Bian, Joseph Subotnik
We study the spin-dependent stereodynamics of the S + H2 -> SH + H reaction using full-dimensional quantum dynamics calculations with zero total nuclear angular momentum along the…
Angular Momentum Transfer between a Molecular System and a Continuous Circularly Polarized Light Field under the Born-Oppenheimer Framework
Xuezhi Bian, Joseph Subotnik
We demonstrate (both analytically and numerically) total angular momentum conservation for a molecular system subject to circularly polarized light (CPL) field moving along a singl…
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…
A Simple One-Electron Expression for Electron Rotational Factors
Tian Qiu, Mansi Bhati, Zhen Tao +4
Within the context of FSSH dynamics, one often wishes to remove the angular component of the derivative coupling between states and . In a set of p…
