Aharonov-Bohm oscillations of electrical and thermal properties of a quantum dot ring geometry
نویسندگان
چکیده
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 ux dependence of the thermopower S and nd that it changes sign with temperature. At the temperature where S(T0) = 0, the thermal properties are strongly ux dependent as compared to the electrical conductance.

In this paper we study the Aharonov-Bohm oscillations of transmission coefficient for an electron passing through a quantum nanoring with two identical magnetic impurities using quantum waveguide theory. It is shown that the Aharonov-Bohm oscillations are independent of the coupling constant between the electron and magnetic impurities for the singlet spin state of impurities, while for the o...

In this paper, we study the electronic properties of a concentric triple quantum ring using exact diagonalization technique. The energy spectra and magnetization for a single electron and two electrons, in the presence of an applied magnetic field, are calculated and discussed. It is shown that, for two-interacting electrons, the period of Aharonov-Bohm oscillations decreases to the half of tha...
متن کاملCoherent coupling of two quantum dots embedded in an Aharonov - Bohm ring
We define two laterally gated small quantum dots (∼ 15 electrons) in an Aharonov-Bohm geometry in which the coupling between the two dots can be broadly changed. For weakly coupled quantum dots we find Aharonov-Bohm oscillations. In an intermediate coupling regime we concentrate on the molecular states of the double dot and extract the magnetic field dependence of the coherent coupling.
متن کاملAharonov-Bohm oscillations in a mesoscopic ring with a quantum dot.
We present an analysis of the Aharonov-Bohm oscillations for a mesoscopic ring with a quantum dot inserted in one of its arms. It is shown that mi-croreversibility demands that the phase of the Aharonov-Bohm oscillations changes abruptly when a resonant level crosses the Fermi energy. We use the Friedel sum rule to discuss the conservation of the parity of the oscillations at different conducta...
متن کاملBohm-Aharonov and Kondo effects on tunneling currents in a mesoscopic ring
We present an analysis of the Kondo effect on the Bohm-Aharonov oscillations of the tunneling currents in a mesoscopic ring with a quantum dot inserted in one of its arms. The system is described by an Andersonimpurity tight-binding Hamiltonian where the electron-electron interaction is restricted to the dot. The currents are obtained using nonequilibrium Green functions calculated through a cu...
