Andreev reflection eigenvalue density in mesoscopic conductors.

Full counting statistics of Andreev scattering in an asymmetric chaotic cavity

We study the charge transport statistics in coherent two-terminal double junctions within the framework of the circuit theory of mesoscopic transport. We obtain the general solution of the circuit-theory matrix equations for the Green’s function of a chaotic cavity between arbitrary contacts. As an example we discuss the full counting statistics and the first three cumulants for an open asymmet...

Circuit theory for crossed Andreev reflection and nonlocal conductance

Nonlocal currents, in devices where two normal-metal terminals are contacted to a superconductor, are determined using the circuit theory of mesoscopic superconductivity. We calculate the conductance associated with crossed Andreev reflection and electron transfer between the two normal-metal terminals, in addition to the conductance from direct Andreev reflection and quasiparticle tunneling. D...

Shot Noise of Mesoscopic Ns Structures : the Role of Andreev Reflection

Shot noise in mesoscopic systems

This is a review of shot noise, the time-dependent fluctuations in the electrical current due to the discreteness of the electron charge, in small conductors. The shot-noise power can be smaller than that of a Poisson process as a result of correlations in the electron transmission imposed by the Pauli principle. This suppression takes on simple universal values in a symmetric double-barrier ju...

Quantum Mesoscopic Scattering: Disordered Systems and Dyson Circular Ensembles

We consider elastic reflection and transmission of electrons by a disordered system characterized by a 2N ×2N scattering matrix S. Expressing S in terms of the N radial parameters and of the four N×N unitary matrices used for the standard transfer matrix parametrization, we calculate their probability distributions for the circular orthogonal (COE) and unitary (CUE) Dyson ensembles. In this par...
