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…

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…

The ground state of the Kondo lattice

Igor N. Karnaukhov

The Kondo insulator state (KIS) is among the least understood phase state in condensed matter physics. KIS is the state of the electron liquid in the Kondo lattice at half filling,…

Gapped electron liquid state in the symmetric Anderson lattice, Kondo insulator state

Igor N. Karnaukhov

The Kondo insulator state (KIS) realized in the symmetric Anderson model at half filling is studied in the framework of a mean field approach. It is shown that the state of the Kon…

Exactly solvable model of topological insulator realized on spin-1/2 lattice

Igor N. Karnaukhov, Igor O. Slieptsov

In this paper we propose an exactly solvable model of a topological insulator defined on a spin-1/2 square decorated lattice. Itinerant fermions defined in the framework of the Hal…
