Quantum coherence with various parameters in the two site XYZ model with DM interactions in the y-direction. (a) Dependence on temperature for different J _y with D _y  = 1, J _x  = −1 and J _z  = −0.5. (b) Dependence on J _y for different temperatures with D _y  = 1, J _x  = −1 and J _z  − 0.5. (c) Dependence on J _x for different temperatures with J _y  = 0.2 and J _z  = −0.5 and D _y  = 1. (d) Dependence on D _y for different temperatures with J _x  = −1, J _y  = 0.2 and J _z  = −0.5. The same results are obtained for quantum coherence in the x-direction for parameters J _x  → J _y , J _y  → J _x , J _z  → J _z and the same temperature.
