Query: Fundamental connection between temperature-quenched 2D superfluids and
  2D quantum turbulence   There is a fundamental connection between temperature-quenched 2D superfluids
and 2D quantum turbulence: the mechanism responsible for the decay of the
vorticity after the quench is the enstrophy cascade of 2D turbulence. The range
of the cascade is shown to increase with time after the quench as $t^{1/2}$,
being equal to the dynamic scaling length characterizing the quench. These
results may apply to other phase-ordering transitions involving the decay of
topological objects.
