An Overview of Self-Consistent Field Calculations Within Finite Basis Sets [PDF]
A uniform derivation of the self-consistent field equations in a finite basis set is presented. Both restricted and unrestricted Hartree−Fock (HF) theory as well as various density functional approximations are considered. The unitary invariance of

Field emission: calculations supporting a new methodology of comparing theory with experiment
This paper provides a demonstration-of-concept of a new methodology for comparing field electron emission (FE) theory and experiment. It uses the parameter κ in the mathematical equation Im = CVmκ exp[–B/Vm] (where B and C are weakly varying or constants)

Effective field theory calculations in open charm and charmonium production in media [PDF]
Heavy quarkonium related observables are very useful to obtain information about the medium created in relativistic heavy ion collisions. The interaction of charmonium or bottomonium with the hot QCD medium created in these collisions can be efficiently ...

Higher-order sensitivity analysis of periodic 3-D eigenvalue problems for electromagnetic field calculations [PDF]
An algorithm to perform a higher-order sensitivity analysis for electromagnetic eigenvalue problems is presented. By computing the eigenvalue and eigenvector derivatives, the Brillouin Diagram for periodic structures can be calculated.
