Quantum correlations versus spin magnitude: Transition to the classical limit
M. A. Yurischev, E. I. Kuznetsova, Saeed Haddadi
Quantum-classical transitions have long attracted much attention. We study such transitions in quantum spin-(,1/2) systems at thermal equilibrium. Unlike the previous work [Phys…
Quantum correlations in general qubit-qudit axially symmetric states
Saeed Haddadi, Elena I. Kuznetsova, M. A. Yurischev
The development and improvement of analytical methods for evaluating nonclassical correlations is one of the most important tasks in quantum information science. In this paper, we…
A comparative study of LQU and LQFI in general qubit-qutrit axially symmetric states
M. A. Yurischev, Saeed Haddadi, Mehrdad Ghominejad
We derive the compact closed forms of local quantum uncertainty (LQU) and local quantum Fisher information (LQFI) for hybrid qubit-qutrit axially symmetric (AS) states. This allows…
Local quantum Fisher information and local quantum uncertainty for general X-states
M. A. Yurischev, Saeed Haddadi
A two-spin-1/2 Heisenberg XYZ model with Dzyaloshinsky--Moriya (DM) and Kaplan--Shekhtman--Entin-Wohlman--Aharony (KSEA) interactions in the presence of an inhomogeneous external m…
Landau-type sudden transitions of quantum correlations
Mikhail A. Yurischev
Sudden changes of quantum correlations in the Bell-diagonal states are well-known effects. They occur when the set of optimal parameters that determine the quantum correlation cons…
Quantum entanglement in the anisotropic Heisenberg model with multicomponent DM and KSEA interactions
A. V. Fedorova, M. A. Yurischev
Using group-theoretical approach we found a family of four nine-parameter quantum states for the two-spin-1/2 Heisenberg system in an external magnetic field and with multiple comp…
