Remark on "Conductance and Shot Noise for Particles with Exclusion Statistics" by Isakov, Martin, and Ouvry

Isakov, Martin, and Ouvry [PRL 83, 580 (1999)] have recently proposed a fresh approach to the potential observation of fractional exclusion statistics. According to their argument, a clear signature of fractional statistics should exist in the shot noise of a Luttinger fluid, an ideal system postulated by some to underlie the well-founded Laughlin quasiparticle states of the two-dimensional electron gas. We elaborate on some delicate points made by Isakov et al. and reflect upon the relationship between this novel intuitive scheme and certain old issues of first principles.
