Query: Dual cascade and dissipation mechanisms in helical quantum turbulence   While in classical turbulence helicity depletes nonlinearity and can alter
the evolution of turbulent flows, in quantum turbulence its role is not fully
understood. We present numerical simulations of the free decay of a helical
quantum turbulent flow using the Gross-Pitaevskii equation at high spatial
resolution. The evolution has remarkable similarities with classical flows,
which go as far as displaying a dual transfer of incompressible kinetic energy
and helicity to small scales. Spatio-temporal analysis indicates that both
quantities are dissipated at small scales through non-linear excitation of
Kelvin waves and the subsequent emission of phonons. At the onset of the decay,
the resulting turbulent flow displays polarized large scale structures and
unpolarized patches of quiescense reminiscent of those observed in simulations
of classical turbulence at very large Reynolds numbers.
