The Schwinger-Keldysh Coset Construction
Can Onur Akyuz, Garrett Goon, Riccardo Penco
The coset construction is a tool for systematically building low energy effective actions for Nambu-Goldstone modes. This technique is typically used to compute time-ordered correl…
Quantum Corrections to Generic Branes: DBI, NLSM, and More
Garrett Goon, Scott Melville, Johannes Noller
We study quantum corrections to hypersurfaces of dimension embedded in generic higher-dimensional spacetimes. Manifest covariance is maintained throughout the analysis and…
A Universal Relation Between Corrections to Entropy and Extremality
Garrett Goon, Riccardo Penco
Perturbative corrections to General Relativity alter the expressions for both the entropy of black holes and their extremality bounds. We prove a universal relation between the lea…
Primordial Non-Gaussianity
P. Daniel Meerburg, Daniel Green, Muntazir Abidi +175
Our current understanding of the Universe is established through the pristine measurements of structure in the cosmic microwave background (CMB) and the distribution and shapes of…
Shapes of gravity: Tensor non-Gaussianity and massive spin-2 fields
Garrett Goon, Kurt Hinterbichler, Austin Joyce +1
If the graviton is the only high spin particle present during inflation, then the form of the observable tensor three-point function is fixed by de Sitter symmetry at leading order…
The Effective Theory of Shift-Symmetric Cosmologies
Bernardo Finelli, Garrett Goon, Enrico Pajer +1
A shift symmetry is a ubiquitous ingredient in inflationary models, both in effective constructions and in UV-finite embeddings such as string theory. It has also been proposed to…
