Kosterlitz-Thouless-type metal-insulator transition in two-dimensional layered media with long-range correlated disorder

We study the transport properties of two-dimensional striped media in the x-y plane with disorder that has long-range correlation along the y-direction. This long-range correlation is reflected by a special form of the Fourier transformation of the spatial distribution of the site energies S(k)1/k with k being the wave vector in the y-direction. Using the transfer-matrix method, we show that there is a continuous line of fixed points for >2 indicating that the system undergoes a disorder-driven Kosterlitz-Thouless-type metal-insulator transition.
