Abstract

We study the noise properties of ballistic conductors with carriers satisfying fractional exclusion statistics. To test directly the nature of exclusion statistics we found that systems under weakly degenerate conditions should be considered. Typical of these systems is that the chemical potential, μ\mu is in the thermal range μ<3kBT|\mu |<3k_{B}T. In these conditions the noise properties under current saturation are found to depend upon the statistical parameter gg, displaying suppressed shot noise for 1/2g11/2\leq g\leq 1, and enhanced shot noise for 0<g<1/20<g<1/2, according to the attractive or repulsive nature of the carrier exclusion statistics.
