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…

The resistance of quantum entanglement to temperature in the Kugel-Khomskii model
V. E. Valiulin, A. V. Mikheyenkov, N. M. Chtchelkatchev +1
The Kugel--Khomskii model with entangled spin and orbital degrees of freedom is a good testing ground for many important features in quantum information processing, such as robust…
