Resonance in an open quantum dot system with a Coulomb interaction: a Bethe-ansatz approach
Abstract
An open quantum system consisting of a quantum dot with a Coulomb interaction and two leads without interactions is studied. The many-body scattering states are constructed with the Bethe-ansatz approach. The expectation value of the electric current is exactly calculated for the scattering states to observe resonance peaks due to many-body scattering.
