Full counting statistics of Andreev tunneling.

چکیده
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 electron that triggers an avalanche of Andreev events giving rise to strongly super-Poissonian distributions.

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...
متن کاملElementary Andreev processes in a driven superconductor–normal metal contact
We investigate the full counting statistics of a voltage driven normal metal(N) superconductor (S) contact. In the low bias regime below the superconducting gap, the NS contact can be mapped onto a purely normal contact, albeit with doubled voltage and counting fields. Hence in this regime the transport characteristics can be obtained by the corresponding substitution of the normal metal result...
متن کاملFull 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...
متن کاملFull 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 ...
متن کاملFull Counting Statistics of a Superconductor/ferromagnet Entangler
We consider the production of spatially separated entangled electrons in transport between a superconductor and ferromagnets: Spin singlet Cooper pairs are filtered into different leads by spin dependent tunneling. We find the full counting statistics depending on the magnetizations and identify the probabilities for productions of entangled electrons taking into account the superconducting pro...
