Inflaton Entanglement

This research explores some interesting observable signatures that could come from initial state entanglement of the inflation.

1) Cosmological Consequences of Initial State Entanglement

2) Modifications to Cosmological Power Spectra from Scalar-Tensor Entanglement and their Observational Consequences

3) Cosmic Inflation: The Most Powerful Microscope in the Universe

4) Non-Gaussianity from Entanglement During Inflation
