Abstract

Through an extension of the Landauer formula, we study the electron transport in an open quantum dot system under a finite bias voltage. The system that we study is an interacting resonant-level model equipped with infinite two leads of a linearized dispersion relation. We explicitly construct many-electron scattering eigenstates whose incident states are free-fermionic. A remarkable feature of the scattering state is the appearance of many-body bound states after the scattering. Extending Landauer’s idea, we calculate the average electric current flowing through the quantum dot. We use a renormalization-group technique to deal with the divergences that appear in the limit of the large bandwidth of the leads. As a result, the average electric current is brought to a universal form.
