Delocalization and conductance quantization in one-dimensional systems
We investigate the delocalization and conductance quantization in finite onedimensional chains with only off-diagonal disorder coupled to leads. It is shown that the appearence of delocalized states at the middle of the band under correlated disorder is strongly dependent upon the even-odd parity of the number of sites in the system. In samples with inversion symmetry the conductance equals 2e/...
متن کاملEffect of coupling to the leads on the conductance fluctuations in one-dimensional disordered, mesoscopic systems
We study the electronic transport in a one-dimensional disordered chair with bath site-diagonal and off-diagonal (hopping) disorder, the latter being perfectly correlated ta the diagonal disorder at the nearest neighbor sites in a linear fashion. Since we allow the hopping m the perfect leads ta be dilferent from the average hopping in the sample, the
متن کاملQuantization of the Hall Conductance and Delocalization in Ergodic Landau Hamiltonians
We prove quantization of the Hall conductance for continuous ergodic Landau Hamiltonians under a condition on the decay of the Fermi projections. This condition and continuity of the integrated density of states are shown to imply continuity of the Hall conductance. In addition, we prove the existence of delocalization near each Landau level for these two-dimensional Hamiltonians. More precisel...
متن کاملPossible mechanism of the fractional conductance quantization in a one-dimensional constriction
As it is well known there may arise situations when an interaction between electrons is attractive. A weak attraction should manifest itself strongly in 1D systems, since it can create two-electron bound states. This paper interprets the 0.7 (2e/h) conductance structure, observed recently in a one-dimensional constriction, as a manifestation of two-electron bound states formed in a barrier sadd...
متن کاملDelocalization of relativistic dirac particles in disordered one-dimensional systems and its implementation with cold atoms.
We study theoretically the localization of relativistic particles in disordered one-dimensional chains. It is found that the relativistic particles tend to delocalization in comparison with the nonrelativistic particles with the same disorder strength. More intriguingly, we reveal that the massless Dirac particles are entirely delocalized for any energy due to the inherent chiral symmetry, lead...
