Short Range Interaction Effects on the Density of States of Disordered Two Dimensional Crystals with a half--filled band
E. P. Nakhmedov, V. N. Prigodin
The Density of electronic States (DoS) of a two--dimensional square lattice with substitutional impurities is calculated in the presence of short--range electron--electron interact…
Mesoscopic fluctuations of the Density of States and Conductivity in the middle of the band of Disordered Lattices
E. P. Nakhmedov, V. N. Prigodin, E. Sasioglu
The mesoscopic fluctuations of the Density of electronic States (DoS) and of the conductivity of two- and three- dimensional lattices with randomly distributed substitutional impur…
Distribution of time-constants for tunneling through a 1D Disordered Chain
C. J. Bolton-Heaton, C. J. Lambert, Vladimir I. Falko +2
The dynamics of electronic tunneling through a disordered 1D chain of finite length is considered. We calculate distributions of the transmission coefficient T, Wigner delay time a…
Hopping Conductivity of a Nearly-1d Fractal: a Model for Conducting Polymers
A. N. Samukhin, V. N. Prigodin, L. Jastrabik +1
We suggest treating a conducting network of oriented polymer chains as an anisotropic fractal whose dimensionality D=1+εis close to one. Percolation on such a fractal is studied wi…
Conductivity fluctuations in polymer's networks
A. N. Samukhin, V. N. Prigodin, L. Jastrabik
Polymer's network is treated as an anisotropic fractal with fractional dimensionality D = 1 + εclose to one. Percolation model on such a fractal is studied. Using the real space re…
Long-Range Spatial Correlations of Eigenfunctions in Quantum Disordered Systems
V. Prigodin, B. L. Altshuler
This paper is devoted to the statistics of the quantum eigenfunctions in an ensemble of finite disordered systems (metallic grains). We focus on moments of inverse participation ra…
Critical Percolation and Transport in Nearly One Dimension
A. N. Samukhin, V. N. Prigodin, L. Jastrabik +1
A random hopping on a fractal network with dimension slightly above one, , is considered as a model of transport for conducting polymers with nonmetallic conductivity. W…
Distribution of the Absorption by Chaotic States in Quantum Dots
Nobuhiko Taniguchi, Vladimir N. Prigodin
The mesoscopic fluctuations of the absorption at optical transitions from a low energy regular state to high energy chaotic states in an aggregate of semiconductor quantum dots is…
Resonant Andreev Scattering In Phase-Coherent, Superconducting Nanostructures
N. R. Claughton, M. Leadbeater, C. J. Lambert +1
Analytic predictions for resonant transport in three generic structures are presented. For a structure comprising a normal (N) contact - normal dot (NDOT) - superconducting (S) con…
Sensitivity of quantum chaotic wavefunction intensities to changes in external perturbations
E. R. Mucciolo, B. D. Simons, A. V. Andreev +1
We examine the sensitivity of wavefunction intensities in chaotic quantum systems to small changes in an arbitrary external perturbation. A universal scaling is proposed for all th…
Spatial Correlation in Quantum Chaotic Systems with Time-reversal Symmetry: Theory and Experiment
V. N. Prigodin, N. Taniguchi, A. Kudrolli +2
The correlation between the values of wavefunctions at two different spatial points is examined for chaotic systems with time-reversal symmetry. Employing a supermatrix method, we…
Statistical Properties of Level Widths and Conductance Peaks in a Quantum Dot
E. R. Mucciolo, V. N. Prigodin, B. L. Altshuler
We study the statistics of level widths of a quantum dot with extended contacts in the absence of time-reversal symmetry. The widths are determined by the amplitude of the wavefunc…
