De Sitter Observers and an Effective Field Theory of Horizon Edge Modes
James Bonifacio, Kurt Hinterbichler, Y. T. Albert Law +1
We show that choosing a test observer in , specified by the framed embedding of their horizon , spontaneously breaks the de Sitter and internal sphere isometries to…
Moduli Bounds from Spin-2 Sum Rules
Francesco Bertucci, James Bonifacio, Kurt Hinterbichler
Mirbabayi and Villadoro have provided strong numerical evidence for a universal upper bound on the mass of the lightest scalar field in gravitational Kaluza--Klein (KK) theories. T…
Bootstrapping Euclidean Lattices
Francesco Bertucci, James Bonifacio
We derive spectral identities involving the Laplace spectrum and the integrals of products of eigenfunctions on flat tori and orbifolds. Using semidefinite programming, we derive u…

Let be holomorphic modular forms of the same weight for a cocompact lattice . We estimate the rate of decay of the coefficients in the expa…
Fermionic Shift Symmetries in (Anti) de Sitter Space
James Bonifacio, Kurt Hinterbichler
We study extended shift symmetries that arise for fermionic fields on anti-de Sitter (AdS) space and de Sitter (dS) space for particular values of the mass relative to the curvatur…

James Bonifacio, Dalimil Mazac, Sridip Pal
We constrain the low-energy spectra of Laplace operators on closed hyperbolic manifolds and orbifolds in three dimensions, including the standard Laplace-Beltrami operator on funct…
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…
Exceptional scalar theories in de Sitter space
James Bonifacio, Kurt Hinterbichler, Austin Joyce +1
The special galileon and Dirac-Born-Infeld (DBI) theories are effective field theories of a single scalar field that have many interesting properties in flat space. These theories…
Bootstrapping Closed Hyperbolic Surfaces

The eigenvalues of the Laplace-Beltrami operator and the integrals of products of eigenfunctions and holomorphic -differentials satisfy certain consistency conditions on closed…
Bootstrap Bounds on Closed Hyperbolic Manifolds
James Bonifacio
The eigenvalues of the Laplace-Beltrami operator and the integrals of products of eigenfunctions must satisfy certain consistency conditions on compact Riemannian manifolds. These…
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.…
Bootstrap Bounds on Closed Einstein Manifolds
James Bonifacio, Kurt Hinterbichler
A compact Riemannian manifold is associated with geometric data given by the eigenvalues of various Laplacian operators on the manifold and the triple overlap integrals of the corr…
Amplitudes and 4D Gauss-Bonnet Theory
James Bonifacio, Kurt Hinterbichler, Laura A. Johnson
It has recently been argued that there may be a nontrivial four-dimensional limit of the higher-dimensional Gauss--Bonnet and Lovelock interactions and that this might provide a lo…
Matter Couplings and Equivalence Principles for Soft Scalars
James Bonifacio, Kurt Hinterbichler, Laura A. Johnson +2
Scalar effective field theories with enhanced soft limits behave in many ways like gauge theories and gravity. In particular, symmetries fix the structure of interactions and the t…

We study the perturbative unitarity of scattering amplitudes in general dimensional reductions of Yang-Mills theories and general relativity on closed internal manifolds. For the t…

We construct a class of extended shift symmetries for fields of all integer spins in de Sitter (dS) and anti-de Sitter (AdS) space. These generalize the shift symmetry, galileon sy…
