# Computational implementation of the Kubo formula for the static conductance: Application to two-dimensional quantum dots

## Description

Abstract Kubo formula is used to get the DC conductance of a statistical ensemble of two-dimensional clusters of the square lattice in the presence of standard diagonal disorder, a uniform magnetic field and random magnetic fluxes. Working within a one-band tight-binding approach the calculation is quite general. The shape of the cluster is rectangular with ideal leads attached to opposite corners. Both geometrical characteristics and physical parameters can be easily selected. The output is just the ... Title of program: KUBO Catalogue Id: ADKI_v1_0 Nature of problem Conductance evaluation plays a central role in the study of the physical properties of quantum dots [1]. The finite mesoscopic system under study is connected to infinite leads defining an infinitesimal voltage drop. Kubo formula is used for the conductance calculation once the Green function of the whole system is known. Dependence of the conductance on the number of conducting modes in the leads, size and shape of the dot, Fermi energy, presence of conventional diagonal disorder or random magn ...
