SECTION 5, 2010.1742-65881742-6596http://hdl.handle.net/11449/71889We discuss the thermal dependence of the zero-bias electrical conductance for a quantum dot embedded in a quantum wire, or side-coupled to it. In the Kondo regime, the temperature-dependent conductances map linearly onto the conductance for the symmetric Anderson Hamiltonian. The mapping fits accurately numerical renormalization-group results for the conductance in each geometry. In the side-coupled geometry, the conductance is markedly affected by a gate potential applied to the wire; in the embedded geometry, it is not. © 2010 IOP Publishing Ltd.engAnderson HamiltonianAnderson modelsElectrical conductanceGate potentialsKondo regimeQuantum DotQuantum wiresRenormalization groupTemperature dependentThermal dependencesZero-biasWireComputational geometryTrabalho apresentado em evento10.1088/1742-6596/200/5/052020Acesso aberto2-s2.0-779570365480097996544293892
