Current cross-correlations in a quantum Hall collider at filling factor two

Abstract

We use the non-equilibrium bosonization technique to study the effects of Coulomb interactions in mesoscopic electron colliders based on quantum Hall (QH) edge states at filing factor $\nu =2$. The current cross-correlations and Fano factor, which carry the information about the exclusion statistics, are calculated. It is shown that both these quantities have a non-analytical dependence on the source transparency, which scales as $\log (1/T_s)$ at small $T_s\ll 1$. This is the consequence of electron-electron interactions in the outgoing non-equilibrium states of the collider.
