  Scalar metric fluctuations generically source a spectrum of gravitational
waves at second order in perturbation theory, poising gravitational wave
experiments as potentially powerful probes of the small-scale curvature power
spectrum. We perform a detailed study of the imprint of primordial
non-Gaussianity on these induced gravitational waves, emphasizing the role of
both the disconnected and connected components of the primoridal trispectrum.
Specializing to local-type non-Gaussianity, we numerically compute all
contributions and present results for a variety of enhanced primordial
curvature power spectra.
