The Chern states on the honeycomb and Lieb lattices
Igor N. Karnaukhov, Igor O. Slieptsov
The Haldane model of the Chern insulator is considered on the Lieb and honeycomb lattices. We provide a detailed analysis of the model's ground-state phase diagram and demonstrate…
Colossal magnetoresistance in topological Kondo insulator
Igor O. Slieptsov, Igor N. Karnaukhov
Abnormal electronic properties of complex systems require new ideas concerning explanation of their behavior and possibility of realization. In this acticle we show that a colossal…
Giant magnetoresistance of edge current between fermion and spin topological systems
Igor O. Slieptsov, Igor N. Karnaukhov
A spin- subsystem conjoined along a cut with a subsystem of spinless fermions in the state of topological insulator is studied on a honeycomb lattice. The model descri…
Exactly solvable 2D topological Kondo lattice model
Igor N. Karnaukhov, Igor O. Slieptsov
A spin- Kitaev sublattice interacting with a subsystem of spinless fermions is studied on a honeycomb lattice when the fermion band is half filled. The model Hamiltoni…
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…
