Altermagnetism without a long-range order
V. E. Valiulin, A. V. Mikheyenkov, K. I. Kugel
The Kugel-Khomskii spin-pseudospin model, originally developed for transition-metal compounds with orbital degrees of freedom, has recently been reinterpreted in the context of alt…
Time-dependent exchange creates the time-frustrated state of matter
V. E. Valiulin, N. M. Chtchelkatchev, A. V. Mikheyenkov +1
Magnetic systems governed by exchange interactions between magnetic moments harbor frustration that leads to ground state degeneracy and results in the new topological state often…
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…
