Full Counting Statistics with Spin-sensitive Detectors reveals Spin-singlets
arXiv:cond-mat/0408377 · doi:10.1103/PhysRevLett.94.210601
Abstract
We study the full counting statistics of electric current to several drain terminals with spin-dependent entrance conductances. We show that the statistics of charge transfers can be interpreted in terms of single electrons and spin-singlet pairs coming from the source. If the source contains transport channels of high transparency, a significant fraction of electrons comes in spin-singlet pairs.
