Fig. 1: Visualisation of a quantum turbulent vortex tangle.
From: Vortex clustering, polarisation and circulation intermittency in classical and quantum turbulence

Instantaneous state obtained from GP simulations using 20483 collocation points. Green and yellow colours correspond to opposite orientations of the vortex lines with respect to the vertical direction. The inset shows a horizontal two-dimensional cut of the system. See “Methods” for the vortex identification algorithm.
