The Ueda-Guinea model of a dissipative tunnel junction is investigated. This model accounts for final-state effects associated with single-electron tunneling. A quantum phase transition emerges, marking a boundary betweeninsulating (Coulomb blockade) and conducting phases. The system is analyzed by large-N techniques, self-consistent harmonic approximation, and Monte Carlo methods.
