1 0 A pr 2 01 7 Full counting statistics of information content and particle number
We consider a bipartite quantum conductor and discuss the joint probability distribution of particle number in a subsystem and the self-information associated with the reduced density matrix of the subsystem. By extending the multi-contour Keldysh Green function technique, we calculate the Rényi entropy of a positive integer order M subjected to the particle number constraint, from which we der...
متن کاملFull Counting Statistics and Field Theory
The concept of Full Counting Statistics has been introduced in very early days of quantum transport. That time, nobody ever thought of such an abstract and complicated problem as the evaluating and measuring the higher cumulants of electronic noise. The research has been driven by pure curiosity and has resulted in compact and deep Levitov formula.[1] The significance of this contribution has b...
متن کاملFull 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...
متن کاملFull 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 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 ...
