A local Fock-exchange potential in Kohn-Sham equations
T. W. Hollins, S. J. Clark, K. Refson +1
We derive and employ a local potential to represent the Fock exchange operator in electronic single-particle equations. This local Fock-exchange (LFX) potential is very similar to…
Multiband one-dimensional electronic structure and spectroscopic signature of Tomonoga-Luttinger liquid behavior in KCrAs
M. D. Watson, Y. Feng, C. W. Nicholson +8
We present Angle-Resolved Photoemission Spectroscopy measurements of the quasi-one dimensional superconductor KCrAs. We find that the Fermi surface contains two Fermi s…
The Ag...Ag dispersive interaction and exotic physical properties of Ag3Co(CN)6
Hong Fang, Martin T. Dove, Keith Refson
We report a density functional theory (DFT) study of Ag3Co(CN)6, a material noted for its colossal positive and negative thermal expansion, and its giant negative linear compressib…
Optimized Effective Potential Using The Hylleraas Variational Method
Tom W. Hollins, Stewart J. Clark, Keith Refson +1
In electronic structure calculations the optimized effective potential (OEP) is a method that treats exchange interactions exactly using a local potential within density-functional…
