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 ν=2\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/Ts)\log(1/T_s) at small Ts1T_s \ll 1. This is the consequence of electron-electron interactions in the outgoing non-equilibrium states of the collider.
