abstract	In a 2048³ simulation of quantum turbulence within the Gross-Pitaevskii equation, it is demonstrated that thelarge-scale motions have a classical Kolmogorov-1941 energy spectrum E(k) ∝ k^−5/3, followed by an energy accumulation with E(k) const at k about the reciprocal mean intervortex distance. This behavior was predicted by the L’vov-Nazarenko-Rudenko bottleneck model of gradual eddy-wave crossover [L’vov, Nazarenko, and Rudenko, J. Low Temp. Phys. 153, 140 (2008)], further developed in the paper.
