Josephson junctions as threshold detectors for full counting statistics.

We discuss how threshold detectors can be used for a direct measurement of the full distribution of current fluctuations and how to exploit Josephson junctions in this respect. We propose a scheme to characterize the full counting statistics from the current dependence of the escape rate measured. We illustrate the scheme with explicit results for tunnel, diffusive, and quasiballistic mesoscopi...

Full counting statistics of Andreev tunneling.

We employ a single-charge counting technique to measure the full counting statistics of Andreev events in which Cooper pairs are either produced from electrons that are reflected as holes at a superconductor-normal-metal interface or annihilated in the reverse process. The full counting statistics consists of quiet periods with no Andreev processes, interrupted by the tunneling of a single elec...

Full counting statistics of multiple Andreev reflections.

We derive the full distribution of transmitted particles through a superconducting point contact of arbitrary transparency under voltage bias. The charge transport is dominated by multiple Andreev reflections. The counting statistics is a multinomial distribution of processes, in which multiple charges ne (n=1,2,3, ...) are transferred through the contact. For zero temperature we obtain analyti...

Full counting statistics of incoherent Andreev transport

– We study the full counting statistics of heterostructures consisting of normalmetal parts connected to a superconducting terminal. Assuming that coherent superconducting correlations are suppressed in the normal metals, we show, using the Keldysh-Nambu Green’s function approach, that the system can be mapped onto a purely normal system with twice the number of elements. For a superconducting ...

Full counting statistics of nano-electromechanical systems

– We develop a theory for the full counting statistics (FCS) for a class of nanoelectromechanical systems (NEMS), describable by a Markovian generalized master equation. The theory is applied to two specific examples of current interest: vibrating C60 molecules and quantum shuttles. We report a numerical evaluation of the first three cumulants for the C60-setup; for the quantum shuttle we use t...
