In some early universe scenarios, a correlation between a long wavelength tensor perturbations with two short wavelength scalar fluctuations may generate an observable signal in form of a quadrupolar power asymmetry. Alternatively, it may produce an off-diagonal contribution to the matter power spectrum which would represent a probe for primordial gravitational waves. We discuss how such intriguing possibilities comes about in specific inflationary models.
