Query: Coulomb blockade with neutral modes   We study transport through a quantum dot in the fractional quantum Hall
regime with filling factors \nu=2/3 and \nu=5/2, weakly coupled to the leads.
We account for both injection of electrons to/from the leads, and quasiparticle
rearrangement processes between the edge and the bulk of the quantum dot. The
presence of neutral modes introduces topological constraints that modify
qualitatively the features of the Coulomb blockade (CB). The periodicity of CB
peak spacings doubles and the ratio of spacing between adjacent peaks
approaches (in the low temperature and large dot limit) a universal value: 2:1
for \nu=2/3 and 3:1 for \nu=5/2. The corresponding CB diamonds alternate their
width in the direction of the bias voltage and allow for the determination of
the neutral mode velocity, and of the topological numbers associated with it.
