  • A generating functional approach to the sd-model with strong correlations 
    Izyumov, Yu.A.; Chaschin, N.I.; Alexeev, D.S. (Condensed Matter Physics, 2005)
    A Kadanoff-Baym-type generating functional approach, earlier developed by the authors to strongly correlated systems, is applied to the sd-model with strong sd-coupling. Formalism of the Hubbard X -operators was used, and ...
  • Sd-model with strong exchange coupling and a metal-insulator phase transition 
    Izyumov, Yu.A.; Chaschin, N.I.; Alexeev, D.S. (Condensed Matter Physics, 2006)
    Sd-exchange model (Kondo lattice model) is formulated for strong sd-coupling within the framework of the Xoperators technique and the generating functional approach. The X-operators are constructed based on the exact ...
