Electron pairing in model with two overlapping bands
Igor N. Karnaukhov
We consider the two-band Hubbard model, where electrons from different bands interact through an on-site one- and two-particle hybridization. The proposed Hamiltonian makes it poss…
-pairing in the model with two-particle hybridization of conduction and localized electrons
Igor N. Karnaukhov
Within the framework of a model, that takes into account two-particle hybridization of conduction and localized electrons, the effective interaction between conduction electrons is…
Solution of the Anderson chain with two-particle hybridization of localized and itinerant electrons
Igor N. Karnaukhov
A modified Anderson lattice is proposed, whose the Hamiltonian accounts for the two-particle hybridization of localized and itinerant electrons instead of one-particle hybridizatio…
Composite Hofstadter bands with Dirac fermion spectrum of fractional quantum Hall states
Igor N. Karnaukhov
The fractional quantum Hall effect (FQHE) is studied in the semiclassical limit in the framework of the Hofstadter model with a short-range interaction between fermions. In the mea…
Solution of one-dimensional Kondo lattice model, ground state calculation
Igor N. Karnaukhov
The ground state of the Kondo chain is calculated taking into account the formation of local singlet states of electrons and moments. Singlets are entangled local states of electro…
Mean field approach plus the Bethe ansatz solution of one dimensional models of Kondo insulator
Igor N. Karnaukhov
The Kondo insulator (KI) is studyed in the frameworrk of one dimensional models of Kondo and symmentic Anderson lattices at half filling. The consistent application of the mean fie…
