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…
On the quantum correlations in two-qubit XYZ spin chains with Dzyaloshinsky-Moriya and Kaplan-Shekhtman-Entin-Wohlman-Aharony interactions
M. A. Yurischev
The anisotropic Heisenberg two-spin-1/2 model in an inhomogeneous magnetic field with both antisymmetric Dzyaloshinsky-Moriya and symmetric Kaplan-Shekhtman-Entin-Wohlman-Aharony c…
Temperature-field phase diagrams of one-way quantum work deficit in two-qubit XXZ spin systems
M. A. Yurischev
The spin-1/2 XXZ chain in a uniform magnetic field at thermal equilibrium is considered. For this model, we give a complete classification of all qualitatively different phase diag…
On the possibility to detect quantum correlation regions with the variable optimal measurement angle
Ekaterina V. Moreva, Marco Gramegna, Mikhail A. Yurischev
Quantum correlations described by quantum discord and one-way quantum deficit can contain ordinary regions with {\em constant} (i.e., universal) optimal measurement angle or $π…
Phase diagram for the one-way quantum deficit of two-qubit X states
M. A. Yurischev
The one-way quantum deficit, a measure of quantum correlation, can exhibit for X quantum states the regions (subdomains) with the phases and which are characterized…
