Momentum distribution of Vinen turbulence in trapped atomic Bose–Einstein condensates [link]Paper  doi  abstract   bibtex   
The decay of multicharged vortices in trapped Bose–Einstein condensates may lead to a disordered vortex state consistent with the Vinen regime of turbulence, characterized by an absence of large-scale flow and an incompressible kinetic energy spectrum \$\$E\textbackslashpropto k\textasciicircum\-1\\$\$. In this work, we study numerically the dynamics of a three-dimensional harmonically trapped Bose–Einstein condensate excited to a Vinen regime of turbulence through the decay of two doubly-charged vortices. First, we study the momentum distribution and observe the emergence of a power-law behavior \$\$n(k)\textbackslashpropto k\textasciicircum\-3\\$\$consistent with the coexistence of wave turbulence. We also study the kinetic energy and particle fluxes, which allows us to identify a direct particle cascade associated with the turbulent stage.
