Understand

We explore the ability of experimental physics to uncover the underlying structure of the gravitational Lagrangian describing inflation.

While the observable degeneracy of the inflationary parameter space is large, future measurements of observables beyond the adiabatic and tensor two-point functions, such as non-Gaussianity or isocurvature modes, might reduce this degeneracy.
We show that even in the absence of such observables, the range of possible inflaton potentials can be reduced with a precision measurement of the tensor spectral index, as might be possible with a direct detection of primordial gravitational waves.

Once the degeneracy is broken, the inflaton potential may be reconstructed, but depending on the model the observable-to-potential mapping might still not be unique. We investigate this inversion problem
