中文摘要	spectral properties of a double quantum dot (qd) structure are studied by a causal green's function (gf) approach. the double qd system is modeled by an anderson-type hamiltonian in which both the intra- and interdot coulomb interactions are taken into account. the gf's are derived by an equation-of-motion method and the real-space renormalization-group technique. the numerical results show that the average occupation number of electrons in the qd exhibits staircase features and the local density of states depends appreciably on the electron occupation of the dot.
