Description
In some early universe scenarios, a correlation between a long-wavelength tensor perturbation 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 possible probe for primordial gravitational waves. We discuss how such intriguing possibilities come about in specific inflationary models.
