Title: Full counting statistics applied to Cooper pair pumping

Abstract:
We investigate geometric charge pumping in superconducting
Josephson devices using the method of Full Counting Statistics.
In previous studies the expectation value of the current operator
was calculated and a very delicate handling of the dissipative master
equation governing the dynamics of the system was required. E.g., the
rotating wave (secular) approximation turned to be non-charge-conserving.
We include the counting field (charge measuring device)
into the master equation and investigate
the influence of voltage fluctuation on the pumping process.
