Abstract
We employ the local quantum uncertainty as reliable quantifier of discord-like correlations of a two-qubit one-dimensional XY Z 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.
