Transmission Resonances Anomaly in 1D Disordered Quantum Systems
A. Eisenbach, Y. Bliokh, V. Freilkher +2
Connections between the electron eigenstates and conductivity of one-dimensional disordered electron systems is studied in the framework of the tight-binding model. We show that fo…
The signature of a double quantum-dot structure in the I-V characteristics of a complex system
L. Bitton, D. Radovsky, A. Cohen +2
We demonstrate that by carefully analyzing the temperature dependent characteristics of the I-V measurements for a given complex system it is possible to determine whether it is co…
Magneto-transport properties of dilute granular ferromagnets
A. Cohen, A. Frydman, R. Berkovits
We present magnetoresistance (MR) measurements performed on quench condensed granular Ni thin films which are on the verge of electric continuity. In these systems the electric con…
Coherent electron transport in a Si quantum dot dimer
L. P. Rokhinson, L. J. Guo, S. Y. Chou +4
We show that the coherence of charge transfer through a weakly coupled double-dot dimer can be determined by analyzing the statistics of the conductance pattern, and does not requi…
The breakdown of the Nagaoka phase in the 2D t-J model
E. Eisenberg, R. Berkovits, D. A. Huse +1
In the limit of weak exchange, J, at low hole concentration, the ground state of the 2D t-J model is believed to be ferromagnetic. We study the leading instability of this Nagaoka…
Localization in Fock space: A finite size scaling hypothesis for many particle excitation statistics
R. Berkovits, Y. Avishai
The concept of localization in Fock space is extended to the study of the many particle excitation statistics of interacting electrons in a two dimensional quantum dot. In addition…
The Conductance in the One Dimensional Spin Polarized Gas
D. Schmeltzer, E. Kogan, R. Berkovits +1
We present a theoretical analysis of the recent experimental results of Thomas et al on transport properties of spin polarized quantum wires. We suggest an explanation of the obser…
Compressibility, capacitance and ground state energy fluctuations in a weakly interacting quantum dot
R. Berkovits, B. L. Altshuler
We study the effect of electron-electron (e-e) interactions on compressibility, capacitance and inverse compressibility of electrons in a quantum dot or a small metallic grain. The…
Even-odd correlations in capacitance fluctuations of quantum dots
O. Prus, A. Auerbach, Y. Aloni +2
We investigate effects of short range interactions on the addition spectra of quantum dots using a disordered Hubbard model. A correlation function \cS(q) is defined on the inverse…
Spectral statistics near the quantum percolation threshold
Richard Berkovits, Yshai Avishai
The statistical properties of spectra of a three-dimensional quantum bond percolation system is studied in the vicinity of the metal insulator transition. In order to avoid the inf…
Interacting electrons in disordered potentials: Conductance versus persistent currents
Richard Berkovits, Yshai Avishai
An expression for the conductance of interacting electrons in the diffusive regime as a function of the ensemble averaged persistent current and the compressibility of the system i…
