Spin-Boson Mappings in the Formalism of -Deformations
Vladimir A. Orlov, Liubov A. Markovich, Andrey V. Mikheyenkov +1
We develop a unified algebraic approach to spin-boson transformations based on the formalism of -deformed oscillators. In the single-mode case, we show that the Holstein-Primako…
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…
Machine learning potential as a guide for eutectic in ultra-refractory multicomponent ceramics
V. E. Valiulin, A. V. Mikheyenkov, N. M. Chtchelkatchev +1
The experimental determination of eutectic points is a long-established and widely used technique, but it is generally only practical for systems with relatively low melting points…
Spherically symmetric approaches in the theoretical study of low-dimensional magnets
A. F. Barabanov, V. E. Valiulin, A. V. Mikheyenkov +1
The main ideas and some of the most important results of the spherically symmetric self-consistent approach and a number of related theoretical algorithms are presented. These meth…
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…
