Andreev scattering and cotunneling between two superconductor-normal metal interfaces : the dirty limit
D. Feinberg
Crossed Andreev reflections and cotunneling occur between two neighbouring superconductor- normal metal or superconducting-ferromagnet interfaces. Previous works assumed a clean BC…
Single Carbon Nanotube--Superconductor Entangler: noise correlations and EPR states
V. Bouchiat, N. Chtchelkatchev, D. Feinberg +3
We propose a device which implements a solid-state nanostructured electron entangler. It consists of a single-walled carbon nanotube connected at both end to normal state electrode…
Using a hybrid superconducting-ferromagnetic tip as a magnetic scanning tunneling microscope
D. Feinberg, G. Deutscher
Approaching a two-component tip made of a superconductor (S) and a ferromagnet (F) from a magnetic sample allows for two distinct tunneling processes between the ferromagnets, thro…
Electron teleportation with quantum dot arrays
O. Sauret, D. Feinberg, Th. Martin
An electron teleportation protocol, inspired by the scenario by Bennett et al., is proposed in a mesoscopic set-up. A superconducting circuit allows to both inject and measure enta…
Transport theory of multiterminal hybrid structures
R. Mélin, D. Feinberg
We derive a microscopic transport theory of multiterminal hybrid structures in which a superconductor is connected to several spin-polarized electrodes. We discuss the non-perturba…
Dynamical mean-field theory of the small polaron
S. Ciuchi, F. de Pasquale, S. Fratini +1
A dynamical mean-field theory of the small polaron problem is presented, which becomes exact in the limit of infinite dimensions. The ground state properties and the one-electron s…
