Abstract

We investigate Aharonov-Bohm oscillations of the electrical current through a strongly correlated quantum dot embedded in an arbitrary scattering geometry in the linear and nonlinear regime. We also study the temperature and flux dependence of the thermopowerS and find that it changes sign with temperature. At the temperature whereS(T 0)=0, the thermal properties are strongly flux dependent as compared to the electrical conductance.
