Abstract
We analytically calculate the scaling exponents of a two-dimensional KPZ-like system: coherently moving incompressible polar active fluids. Using three different renormalization group approxima- tion schemes, we obtain values for the “roughness” exponent χ and anisotropy exponent ζ that are extremely near the known exact results. This implies our prediction for the previously completely unknown dynamic exponent z is likely to be quantitatively accurate.
