Figure 3. The decay of a fully spin polarized state in the frustrated triangular cluster coupled to the reservoir at temperature T = 0.02.

The interaction parameter U is tuned as indicated by different colors. Dynamics of (a) cluster magnetization 〈S_z〉 and (b) cluster occupation 〈N〉 is presented. One can see that tuning U allows to control the relaxation process of the excited state of the cluster.
