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…
