In this note we present a simple but exact model of quasi-single field inflation \cite{Chen:2009zp, Chen:2009we}, in which the couplings between perturbations are completely controlled, and for instance can be made constant with any desired value. This provides a way to numerically implement quasi-single field inflation and to test its predictions in various regimes. We confirm that the numerics agree to good accuracy with the analytical predictions for the isosceles bispectrum and the full shape function.

Origin of ultra-light fields during inflation and their suppressed non-Gaussianity
A scaling symmetry in a class of two-field inflation models naturally produces a massless isocurvature field whose self-interactions are suppressed, making primordial non-Gaussianity slow-roll suppressed but with a sq...
