Failure of mean-field approach in out-of-equilibrium Anderson model
Bertalan Horváth, Bence Lazarovits, Olivier Sauret +1
To explore the limitations of the mean field approximation, frequently used in \textit{ab initio} molecular electronics calculations, we study an out-of-equilibrium Anderson impuri…
Spin noise and Bell inequalities in a realistic superconductor-quantum dot entangler
O. Sauret, T. Martin, D. Feinberg
Charge and spin current correlations are analyzed in a source of spin-entangled electrons built from a superconductor and two quantum dots in parallel. In addition to the ideal (cr…
Realistic operation of an entangler : a density matrix approach
Olivier Sauret, Denis Feinberg, Thierry Martin
The detailed operation of an electron spin entangler is studied, using density matrix equations. The device is made of a superconductor, two quantum dots and two normal leads. The…
Spin current as a probe of interactions in mesoscopic systems
Olivier Sauret, Denis Feinberg
The spin resolved current shot noise can uniquely probe the interactions in mesoscopic systems: i) in a normal-superconducting junction, the spin current noise is zero, as carried…
Quantum master equations for the superconductor--dot entangler
Olivier Sauret, Denis Feinberg, Thierry Martin
The operation of a source of entangled electron spins, based on a superconductor and two quantum dots in parallel\cite{loss}, is described in detail with the help of quantum master…
Spin current shot noise as a probe of interactions in mesoscopic systems
O. Sauret, D. Feinberg
It is shown that the spin resolved current shot noise can probe attractive or repulsive interactions in mesoscopic systems. This is illustrated in two physical situations : i) a no…
