The ground state properties of a one-dimensional system with particle-holesymmetry, consisting of a gate controlled dot coupled to an interactingreservoir, are explored using the numerical DMRG method. It was previouslyshown that the system's thermodynamic properties as a function of the gatevoltage in the Luttinger liquid phase are qualitatively similar to the behaviorof a non-interacting wire with an effective (renormalized) dot-lead coupling.Here we examine the thermodynamic properties of the wire in the charge densitywave phase, and show that these properties behave quite differently. The numberof electrons in the system remains constant as a function of the gate voltage,while the total energy becomes linear. Moreover, by tuning the gate voltage onthe dot in the charge density wave phase it is possible to drive the wirethrough a first order quantum phase transition in which the population of eachsite in the wire is inverted.Comment: 7 pages, 7 figure
