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…
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…
Surface Hopping, Electron Translation Factors, Electron Rotation Factors, Momentum Conservation, and Size Consistency
Vishikh Athavale, Xuezhi Bian, Zhen Tao +5
For a system without spin-orbit coupling, the (i) nuclear plus electronic linear momentum and (ii) nuclear plus orbital electronic angular momentum are good quantum numbers. Thus,…
