Discrete charging of a quantum dot strongly coupled to external leads
Richard Berkovits, Felix von Oppen, Jan W. Kantelhardt
We examine a quantum dot with levels which is strongly coupled to leads for varying number of channels in the leads. It is shown both analytically and numerically…
Density matrix renormalization group study of the charging of a quantum dot strongly coupled to a single lead
Richard Berkovits
A new application of the density matrix renormalization group (DMRG) method to a system composed of an interacting dot coupled to a infinite one dimensional lead is presented. This…
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…
