Query: Evidence for the Luttigger liquid density of states in transport across
  the incompressible stripe at fractional filling factors   We experimentally investigate transport across the incompressible stripe at
the sample edge in the fractional quantum Hall effect regime at bulk filling
factors $\nu=2/3$ and $\nu=2/5$. We obtain the dependence of the equilibration
length, that is a phenomenological characteristics of the transport, on the
voltage imbalance and the temperature, at high voltage imbalances. These
dependencies are found to be of the power-law form, which is a strong evidence
for the Luttigger liquid density of states.
