The random potential acting on the particle originates from equilibrium thermal fluctuations of the ionic charge density, described within the random phase approximation (RPA). The resulting potential correlation function exhibits an unscreened $1/r$ tail at large distances, leading to a logarithmic divergence of the integrated disorder strength.
