Quantum entanglement, local indicators and effect of external fields in the Kugel-Khomskii model
V. E. Valiulin, A. V. Mikheyenkov, N. M. Chtchelkatchev +1
Using the exact diagonalization technique, we determine the energy spectrum and wave functions for finite chains described by the two-spin (Kugel--Khomskii) model with different ty…
Magnetic spiral order in the square-lattice spin system (CuBr)SrNbO
A. V. Mikheyenkov, V. E. Valiulin, A. F. Barabanov
We address quantum spin helical states in the strongly frustrated Heisenberg model. Contrary to conventional Dzyaloshinskii-Moriya approach we show that such states appear without…
Continuous transformation between ferro and antiferro circular structures in frustrated Heisenberg model
V. E. Valiulin, A. V. Mikheyenkov, N. M. Chtchelkatchev +1
Frustrated magnetic compounds, in particular low-dimensional, are topical research due to persistent uncover of novel nontrivial quantum states and potential applications. The prob…
