The effect of a small magnetic flux on the metal-insulator transition
Lukas Jahnke, Jan W. Kantelhardt, Richard Berkovits
We numerically show that very small magnetic flux can significantly shift the metal-insulator transition point in a disordered electronic system. The shift we observe for the 3d An…
A generation-based particle-hole density-matrix renormalization group study of interacting quantum dots
Yuval Weiss, Richard Berkovits
The particle-hole version of the density-matrix renormalization-group method (PH-DMRG) is utilized to calculate the ground-state energy of an interacting two-dimensional quantum do…
Resistance distribution in the hopping percolation model
Yakov M. Strelniker, Shlomo Havlin, Richard Berkovits +1
We study the distribution function, P(rho), of the effective resistance, rho, in two and three-dimensional random resistor network of linear size L in the hopping percolation model…
Statistical Properties of The First Excited State of an Interacting Many Particle Disordered System
Richard Berkovits, Yuval Gefen, Igor V. Lerner +1
The distribution of the first many-body excitation energy of a weakly and moderately interacting electron gas in a finite conductor (in the diffusive regime) is calculated. A…
Study of the Localization Transition on a Cayley-tree via Spectral Statistics
Miri Sade, Richard Berkovits
The spectral statistics of a Cayley-tree is numerically studied. The statistics are non-universal due to the high ratio of boundary sites. Once the boundary sites are connected to…
