Exactness of Symmetry-Broken Self-Interaction Correction in the Strongly-Correlated or Classical Limit: Harmonium as a Demonstration
Cody Woods, Yunzhi Li, Wenqing Yao +2
Strong electron correlation is an important challenge to both wavefunction and density functional theory. It has been argued that the Perdew-Zunger 1981 self-interaction correction…

Exact Constraint of Density Functional Approximations at the Semiclassical Limit
Yunzhi Li, Chen Li
We introduce the semiclassical limit to electronic systems by taking the limit in the solution of Schrödinger equations. We show that this limit is closely re…
