Abstract [en]

The behavior of a simple model was considered that reflected many characteristic features of realistic double quantum dots (QD) with more complicated structure. The system was described in the framework of the S matrix theory by the effective Hamiltonian of the open quantum system. It consisted of the Hamiltonian of the closed system and a term that accounts for the coupling of the states via the continuum of propagating modes in the leads. The results show that the branch points influence strongly the features of transmission through double quantum dots.
