On the Asymptotic Nature of Cosmological Effective Theories
Carlos Duaso Pueyo, Harry Goodhew, Ciaran McCulloch +1
Much of our intuition about Effective Field Theories (EFTs) stems from their formulation in flat spacetime, yet EFTs have become indispensable tools in cosmology, where time-depend…
Perturbative unitarity bounds from momentum-space entanglement
Carlos Duaso Pueyo, Harry Goodhew, Ciaran McCulloch +1
Physical theories have a limited regime of validity and hence must be accompanied by a breakdown diagnostic to establish when they cease to be valid as parameters are varied. For p…
Graviton Trispectrum from Gluons
Connor Armstrong, Harry Goodhew, Arthur Lipstein +1
The tree-level wavefunction coefficient for four gravitons in de Sitter space was recently bootstrapped using the Cosmological Optical Theorem, flat space limit, and Manifestly Loc…
The graviton four-point function in de Sitter space
James Bonifacio, Harry Goodhew, Austin Joyce +2
We compute the tree-level late-time graviton four-point correlation function, and the related quartic wavefunction coefficient, for Einstein gravity in de Sitter spacetime. We deri…
Rational Wavefunctions in de Sitter Spacetime
Harry Goodhew
The Bootstrap approach to calculating cosmological correlators relies on a well motivated ansatz. It is typical in the literature to assume that correlators are rational functions…
Derivative Interactions during Inflation: A Systematic Approach
Aliakbar Abolhasani, Harry Goodhew
We present a systematic prescription for calculating cosmological correlation functions for models with derivative interactions through the wavefunction of the universe and compare…
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…
The Cosmological Optical Theorem
Harry Goodhew, Sadra Jazayeri, Enrico Pajer
The unitarity of time evolution, or colloquially the conservation of probability, sits at the heart of our descriptions of fundamental interactions via quantum field theory. The im…
Backreaction in an analogue black hole experiment
Sam Patrick, Harry Goodhew, Cisco Gooding +1
In general relativity, the interaction between a black hole and the fields around it (a process known as backreaction) proceeds via the evolution of the black holes mass and angula…
