Energy Spectra of Quantum Turbulence

摘要: Abstract We review recent developments in the physics of quantum turbulence. Quantum turbulence is comprised quantised vortices that are definite topological defects, giving a prototype much simpler than conventional model. Recent studies have shown clear similarities and differences between classical Following general introduction this field, chapter discusses energy spectrum at very low temperatures. A key issue transfer from large to small scales. At scales larger mean vortex spacing, obeys Kolmogorov law, transferred through Richardson cascade vortices, which confirmed by numerical analysis using filament model Gross–Pitaevskii This range considered classical. smaller discreteness becomes significant, Kelvin-wave caused nonlinear interactions different wavenumber modes Kelvin-waves excited along single vortex. quantum.
