The squeezed limit of the solid inflation three-point function
  The recently proposed model of 'solid inflation' features a peculiar
three-point function for scalar perturbations with an anisotropic, purely
quadrupolar, squeezed limit. We confirm this result as well as the overall
amplitude of the three point-function via an extremely simple computation,
where we focus on the squeezed limit from the start and follow the standard
logic adopted in deriving the consistency relations. Our system violates the
consistency relations, but in the squeezed limit the three-point function can
still be traded for a background-dependent two-point function, which is
immediate to compute. Additionally, we use these simple methods to derive some
new results - namely, certain squeezed limits of the three-point correlators
involving vector and tensor perturbations as well.
