We calculate the low-energy spectral weight of a holographic superfluid coupled to a Chern-Simons term in IR radial scaling geometries characterized by a parameter η. This work was motivated by previous results where an unexpected low-energy spectral weight and a region of instability were seen, both at finite momentum, for the holographic superfluid. We characterize the effect of varying the Chern-Simons coupling α and condensate charge parameter ζ on these regions supporting low-energy spectral weight or a finite momentum instability. We show that η, α and ζ each plays a unique role in shaping these regions. We find a surface αcrit(η, ζ) above which the theory is unstable. In the longitudinal channel we extend our analysis to general dimension d. We briefly analyze the Einstein-Maxwell-dilaton theory and find that Fermi shells exist for d > 4.
