Query: Conductivity tensor of striped quantum Hall phases   We study the transport properties of pinned striped quantum Hall phases. We
show that under quite general assumptions, the macroscopic conductivity tensor
satisfies a semicircle law. In particular, this result is valid for both
smectic and nematic stripe phases, independent of the presence of topological
defects such as dislocations and grain boundaries. As a special case, our
results explain the experimental validity of a product rule for the dissipative
part of the resistivity tensor, which was previously derived by MacDonald and
Fisher for a perfect stripe structure.
