Query: Incoherent ensemble dynamics in disordered systems   We derive a quantum master equation which describes the dynamics of the
ensemble-averaged state of homogeneous disorder models at short times, and
mediates a transition from coherent superpositions into classical mixtures.
While each single realization follows unitary dynamics, this decoherencelike
behavior arises as a consequence of the ensemble average. The master equation
manifestly reflects the translational invariance of the disorder correlations
and allows us to relate the disorder-induced dynamics to a collisional
decoherence process, where the disorder correlations determine the spatial
decay of coherences. We apply our theory to the (one-dimensional) Anderson
model.
