Active Spaces and Non-Orthogonal Configuration Interaction Approaches for Investigating Molecules on Metal Surfaces
Junhan Chen, Wenjie Dou, Joseph Subotnik
We test a set of multiconfigurational wavefunction approaches for calculating the ground state electron population for a two-site Anderson model representing a molecule on a metal…

On the Meaning of Berry Force For Unrestricted Systems Treated With Mean-Field Electronic Structure
Xuezhi Bian, Tian Qiu, Junhan Chen +1
We show that the Berry force as computed by an approximate, mean-field electronic structure can be meaningful if properly interpreted. In particular, for a model Hamiltonian repres…
