In this article we discuss conductance through a quantum dot in the fractional quantum Hall regime. We argue that in the intermediate temperature regime (F~ .~ kT ~ A) many-body coherence strongly suppresses the conductance well below the integer regime values. In particular, we find that in the u =
The low-frequency resistance noise of quantum point contacts is shown to be dominated by fluctuations in the electrostatic potential. Both in the ballistic and in the quantum Hall regime, the noise is strongly suppressed if the conductance is quantized. The suppression is enhanced by a strong magnet
