Temperature-induced metal-insulator transition in a non-symmetric Hubbard model at half-filling
In the present paper metal-to-insulator transition with the increase of temperature is studied in a narrow-band model with non-equivalent Hubbard subbands at half-filling. It is shown that the results obtained in the considered model are essentially distinct from those obtained in the Hubbard model...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | In the present paper metal-to-insulator transition with the increase of temperature is studied in a narrow-band model with non-equivalent Hubbard
subbands at half-filling. It is shown that the results obtained in the considered model are essentially distinct from those obtained in the Hubbard
model. The results are applied to the interpretation of some experimental
data.
У цій роботі вивчається температурно-індукований перехід метал-діелектрик у вузькозонній моделі з нееквівалентними габбардівськими підзонами при половинному заповненні. Показано, що результати, отримані у розглядуваній моделі, суттєво відрізняються від результатів моделі Габбарда.
