A Differential Representation of Cosmological Wavefunctions
Aaron Hillman, Enrico Pajer
Our understanding of quantum field theory rests largely on explicit and controlled calculations in perturbation theory. Because of this, much recent effort has been devoted to impr…
Bootstrapping Large Graviton non-Gaussianities
Giovanni Cabass, Enrico Pajer, David Stefanyszyn +1
Gravitational interferometers and cosmological observations of the cosmic microwave background offer us the prospect to probe the laws of gravity in the primordial universe. To stu…
From Amplitudes to Contact Cosmological Correlators
James Bonifacio, Enrico Pajer, Dong-Gang Wang
Our understanding of quantum correlators in cosmological spacetimes, including those that we can observe in cosmological surveys, has improved qualitatively in the past few years.…
Cutting Cosmological Correlators
Harry Goodhew, Sadra Jazayeri, Mang Hei Gordon Lee +1
The initial conditions of our universe appear to us in the form of a classical probability distribution that we probe with cosmological observations. In the current leading paradig…
Cosmological Cutting Rules
Scott Melville, Enrico Pajer
Primordial perturbations in our universe are believed to have a quantum origin, and can be described by the wavefunction of the universe (or equivalently, cosmological correlators)…
From Locality and Unitarity to Cosmological Correlators
Sadra Jazayeri, Enrico Pajer, David Stefanyszyn
In the standard approach to deriving inflationary predictions, we evolve a vacuum state in time according to the rules of a given model. Since the only observables are the future v…
