概要
- 論文の詳細を見る
The Hubbard model is investigated by the Hubbard's improved approximation (Hubbard III) with special emphasis on the importance of the resonance broadening process as compared to the CPA. The resonance broadening process gives rise to a strikingly different electronic structure in the Hubbard III for the arbitrary numbers of up and down spin electrons from those given by the CPA. The width of each Hubbard sub-band remains unchanged against the compensation or unbalancing the numbers of up and down spin electrons due to the dynamical motion of electrons of each spin. The behaviour of the system under magnetic fields with deformed Hubbard bands is also discussed.
