摘要：

We employ the local quantum uncertainty as reliable quantifier of discord-like correlations of a two-qubit one-dimensional XYZ Heisenberg chain with Dzyaloshinski-Moriya interaction in thermal equilibrium. We discuss the behavior of quantum correlations in terms of the Dzyaloshinski-Moriya coupling parameter and the temperature of the bath. A special emphasis is devoted to the effects induced by the Dzyaloshinski-Moriya interaction which tend to increase the amount of quantum discord contained in the system.
