Black Hole Mergers as the Fastest Photon Ring Scramblers
D. Giataganas, G. F. Giudice, A. Ianniccari +5
Black holes are the most efficient scramblers in nature. By mapping the instantaneous mass and angular momentum of two spinless black holes in a quasi-circular binary onto those of…
Dual is Different: EFTs, Axions and Nonpropagating Form Fields in Cosmology
C. P. Burgess, F. Quevedo
Scalar fields in 4D are known to have equivalent dual descriptions in terms of form-field gauge potentials, but this is often regarded as an arcane fact. Why use more complicated f…
Steven Weinberg: A Scientific Life
C. P. Burgess, F. Quevedo
Steven Weinberg was a giant of late 20th Century physics on whose shoulders we stand while groping for the science of the 21st Century. This article provides a too-brief summary of…
4D de Sitter from String Theory via 6D Supergravity
C. P. Burgess, F. Muia, F. Quevedo
We obtain de Sitter (dS) solutions from controlled string-theory constructions. We review how minimal gauged chiral 6D supergravity evades standard dS no-go theorems by having a po…
Axio-Chameleons: A Novel String-Friendly Multi-field Screening Mechanism
Philippe Brax, C. P. Burgess, F. Quevedo
Scalar-tensor theories with the shift symmetries required by light scalars are well-explored modifications to GR. For these, two-derivative scalar self-interactions usually dominat…
Light Axiodilatons: Matter Couplings, Weak-Scale Completions and Long-Distance Tests of Gravity
Philippe Brax, Cliff Burgess, Fernando Quevedo
We consider the physical implications of very light axiodilatons motivated by a novel mechanism to substantially reduce the vacuum energy proposed in arXiv:2110.10352. We address t…
