Abstract:
The integer and fractional quantum Hall effect constitute novel states of matter in condensed matter systems in the presence of high magnetic fields, which were uncovered about 4 decades ago. In the context of quantum mesoscopic physics/nanophysics, the first attempts to describe theoretically and measure their transport properties were established in the mid-nineties, yet very exciting ongoing research continues to be performed in this field to this day. I will attempt to describe, through a review of both theory and experiments, how current-current correlations - called noise - allows to uncover the manifestation of their elementary excitations - anyons - which bear both fractional charge and statistics.
