Query: Resistivity anisotropy of quantum Hall stripe phases   Quantum Hall stripe phases near half-integer filling factors $\nu \ge 9/2$
were predicted by Hartree-Fock (HF) theory and confirmed by discoveries of
giant resistance anisotropies in high-mobility two-dimensional electron gases.
A theory of such anisotropy was proposed by MacDonald and Fisher, although they
used parameters whose dependencies on the filling factor, electron density, and
mobility remained unspecified. Here, we fill this void by calculating the
hard-to-easy resistivity ratio as a function of these three variables.
Quantitative comparison with experiment yields very good agreement which we
view as evidence for the "plain vanilla" smectic stripe HF phases.
