Appendix E: Supplementary Notes on Electronic Structure Theory
摘要
In this chapter, we provide an appendix summarizing several technical details related to electronic structure theory. Section 15.1 on the Cusp theorem is motivated by the discussion of the cusp condition equation in the main text (Sect. 8.1.2 ). Section 15.2 on the Twisted boundary condition is motivated by the discussion on finite-size errors in Sect. 9.1.2 .
