Localization of a quantum particle in a classical one-component plasma. II. Dynamic Disorder and Temporal Decorrelation (opens in new tab)

We extend the static theory of disorder-induced exponential decay of the averaged Green function of a quantum charged particle in a classical one-component plasma to the dynamic regime by incorporating the temporal evolution of the ionic density fluctuations within the random phase approximation. The dynamic potential correlator is derived from the fluctuation-dissipation theorem and the Kramers--Kronig relations. Within the eikonal (straight-li...
