Fig. 5: Energy spectra of the colloid dynamics.
From: Simultaneous emergence of active turbulence and odd viscosity in a colloidal chiral active system

Energy spectra obtained from the power-spectral-density of the rotor dynamics as in Eq. (10) divided by the mean-square velocity. Blue bullets depict simulation data whereas red triangles denote experimental data. Dotted and dashed experimental and simulation lines correspond to comparable densities. The experimental data is multiplied by a constant factor to match the high-q simulation values. The minimum and maximum wave numbers are \({q}_{\min }\sigma /(2\pi )=3\times 1{0}^{-3}\) and \({q}_{\max }\sigma /(2\pi )=5\times 1{0}^{-1}\). Statistics here are similar to Fig. 4. Inset: Averaged flow field in a simplified vortex, rotors arranged in a circle of radius Rv, with a fixed separation \(\bar{r}\) between nearest neighbours, with tav = 105 and nav = 80.
