Kolmogorov spectrum of the Gross–Pitaevskii turbulence Original Research Article

The energy spectrum of quantum turbulence is studied numerically by solving the Gross–Pitaevskii equation. We introduce the dissipation term which works only in the scale smaller than the healing length, to remove short wavelength excitations which may hinder the cascade process of quantized vortices in the inertial range. The obtained energy spectrum is consistent with the Kolmogorov law.
