    "abstract": "We study numerically the dynamics of excitons on discrete rings in the\npresence of static disorder. Based on continuous-time quantum walks we compute\nthe time evolution of the Wigner function (WF) both for pure diagonal (site)\ndisorder, as well as for diagonal and off-diagonal (site and transfer)\ndisorder. In both cases, large disorder leads to localization and destroys the\ncharacteristic phase space patterns of the WF found in the absence of disorder.",
