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…
