Three-terminal transport through a quantum dot in the Kondo regime: Conductance, dephasing, and current-current correlations
David Sánchez,Rosa López +1 more
Abstract: We investigate the nonequilibrium transport properties of a three-terminal quantum dot in the strongly interacting limit. At low temperatures, a Kondo resonance arises from the antiferromagnetic coupling between the localized electron in the quantum dot and the conduction electrons in source and drain leads. It is known that the local density of states is accessible through the differential conductance measured at the (weakly coupled) third lead. Here, we consider the multiterminal current-current correlations (shot noise and cross correlations measured at two different terminals). We discuss the dependence of the current correlations on a number of external parameters: bias voltage, magnetic field, and magnetization of the leads. When the Kondo resonance is split by fixing the voltage bias between two leads, the shot noise shows a nontrivial dependence on the voltage applied to the third lead. We show that the cross correlations of the current are more sensitive than the conductance to the appearance of an external magnetic field. When the leads are ferromagnetic and their magnetizations point along opposite directions, we find a reduction of the cross correlations. Moreover, we report on the effect of dephasing in the Kondo state for a two-terminal geometry when the third lead plays the role of a fictitious voltage probe.

Shot noise generated by graphene p-n junctions in the quantum Hall effect regime.
TL;DR: The mixing and partitioning suggest that a p–n junction could be used as an electronic beam splitter and the relaxation length is much larger than typical size of mesoscopic devices, encouraging using graphene for electron quantum optics and quantum information processing.

Dynamic scattering channels of a double barrier structure
TL;DR: In this paper, the authors calculate analytically the Floquet scattering matrix for a periodically driven double-barrier structure, taking into account dynamical effects which become necessarily important when electrons propagate through a system subject to a fast drive.

Shot noise near the unitary limit of a Kondo quantum dot
TL;DR: In this article, the statistics of current fluctuations in a junction with a quantum dot described by Kondo Hamiltonian were examined with the help of Keldysh's technique and shot noise was calculated as a function of applied voltage at zero temperature using the fixed-point Hamiltonian.

Transition from metallic to tunneling regimes in superconducting microconstrictions: Excess current, charge imbalance, and supercurrent conversion
TL;DR: In this paper, the Bogoliubov equations were used to model the transmission and reflection of particles at the tunnel junction of normal-superconducting micro-constriction contacts, and a simple theory for the $I\ensuremath{-}V$ curves of normal superconducting contacts was proposed to describe the crossover from metallic to tunnel junction behavior.
