摘要：
In this research, we investigated the quantum correlation in SU(2) invariant quantum spin systems by using the local quantum uncertainty (LQU). The SU(2) invariant quantum spin states are invariant under global rotations of the subsystems, and in real physical systems, such states arise from states of isotropic spin systems in thermal equilibrium. We derive an analytic expression for the LQU of (2j + 1) aSu 2 and (2j + 1) aSu 3 quantum spin systems with SU(2) symmetry.
