Crossover of high and low spin states in transition metal complexes
Hannes Raebiger, Shuhei Fukutomi, Hiroshi Yasuhara
The stability of high vs. low spin states of transition metal complexes has been interpreted by ligand field theory, which is a perturbation theory of the electron-electron interac…
Interpretation of Hund's multiplicity rule for the carbon atom
Kenta Hongo, Ryo Maezono, Yoshiyuki Kawazoe +3
Hund's multiplicity rule is investigated for the carbon atom using quantum Monte Carlo methods. Our calculations give an accurate account of electronic correlation and obey the vir…
Exchange-correlation energy functional constructed from orbital-dependent coupling-constant-averaged pair correlation functions
Hiroshi Yasuhara, Masahiko Higuchi, Yoshiyuki Kawazoe
An exchange-correlation energy functional and the resultant exchange-correlation potential in density-functional theory are proposed…
A proposal of an orbital-dependent correlation energy functional for energy-band calculations
Masahiko Higuchi, Hiroshi Yasuhara
An explicitly orbital-dependent correlation energy functional is proposed, which is to be used in combination with the orbital-dependent exchange energy functional in energy-band c…
Why is the bandwidth of sodium observed to be narrower in photoemission experiments?
H. Yasuhara, S. Yoshinaga, M. Higuchi
The experimentally predicted narrowing in the bandwidth of sodium is interpreted in terms of the non-local self-energy effect on quasi-particle energies of the electron liquid. The…
