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…

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…
