A conducting 1D chain or 2D film inside (or on the surface of) an insulator is considered. Impurities displace the charges inside the insulator. This results in a long-range fluctuating electric field acting on the conducting line (plane). This field can be modeled by that of randomly distributed electric dipoles. This model provides a random correlated potential with \propto 1/k. In the 1D case such correlations may essentially influence the localization length but do not destroy Anderson…

Effect of long-range correlation on the metal-insulator transition in a disordered molecular crystal
Localization lengths of the electronic states in a disordered two-dimensional system, resembling highly anisotropic molecular crystals such as pentacene, have been calculated numerically using the
Diagonal and off-diagonal types of disorder in condensed matter theory
In the paper we investigate the distribution function of a diagonal type of disorder, their relation with microscopic model parameters and structural correlation functions. The conditions are
Interplay between interaction and (un)correlated disorder in one-dimensional many-particle systems: delocalization and global entanglement
We consider a one-dimensional (1D) quantum many-body system and investigate how the interplay between interaction and on-site disorder affects spatial localization and quantum correlations. The
Ergodic-localized junctions in periodically driven systems
Quantum phases of matter have many relevant applications in quantum computation and quantum information processing. Current experimental feasibilities in diverse platforms allow us to couple two or
