Apparent Fine Tunings for Field Theories with Broken Space-Time Symmetries
Alberto Nicolis, Ira Z. Rothstein
We exhibit a class of effective field theories that have hierarchically small Wilson coefficients for operators that are not protected by symmetries but are not finely tuned. These…
On Causality Conditions in de Sitter Spacetime
Noah Bittermann, Daniel McLoughlin, Rachel A. Rosen
We carefully consider the Shapiro time delay due to black holes and shockwaves in de Sitter spacetime and study the implications for causality. We discuss how causality conditions…
Ladder Symmetries of Black Holes and de Sitter Space: Love Numbers and Quasinormal Modes
Roman Berens, Lam Hui, Zimo Sun
In this note, we present a synopsis of geometric symmetries for (spin 0) perturbations around (4D) black holes and de Sitter space. For black holes, we focus on static perturbation…
Black Hole Horizon Edge Partition Functions
Manvir Grewal, Y. T. Albert Law, Klaas Parmentier
We extend a formula for 1-loop black hole determinants by Denef, Hartnoll, and Sachdev (DHS) to spinning fields on any -dimensional static spherically symmetric black hole.…
Soft theorems for boosts and other time symmetries
Lam Hui, Austin Joyce, Ilia Komissarov +3
We derive soft theorems for theories in which time symmetries -- symmetries that involve the transformation of time, an example of which are Lorentz boosts -- are spontaneously bro…
Cosmology as a weak gravitational field and the trans-Planckian problem
Ilia Komissarov, Alberto Nicolis, John Staunton
At momenta much higher than the Hubble scale, the cosmological expansion can be thought of as a weak gravitational field. We consider QFT in a particularly convenient set of coordi…
Superluminal Propagation on a Moving Braneworld
Brian Greene, Daniel Kabat, Janna Levin +1
We consider a braneworld scenario in the simplest setting, , with a 4D Minkowski metric induced on the brane, and establish the possibility of superluminal propagat…
Towards an "AdSCFT" correspondence from the DD system?
Sergio E. Aguilar-Gutierrez, Klaas Parmentier, Thomas Van Riet
We argue that a type IIB Euclidean supergravity solution of the form with imaginary self-dual flux through be…
Black Hole Scattering and Partition Functions
Y. T. Albert Law, Klaas Parmentier
When computing the ideal gas thermal canonical partition function for a scalar outside a black hole horizon, one encounters the divergent single-particle density of states (DOS) du…
Integer solutions to the anomaly equations for a class of chiral gauge theories
Alessandro Podo, Filippo Revello
We find all the integer charge solutions to the equations for the cancellation of local gauge anomalies in a class of gauge theories which extend the Standard Model (SM) by a gauge…
Integrating out beyond tree level and relativistic superfluids
Austin Joyce, Alberto Nicolis, Alessandro Podo +1
We revisit certain subtleties of renormalization that arise when one derives a low-energy effective action by integrating out the heavy fields of a more complete theory. Usually th…
Near-Zone Symmetries of Kerr Black Holes
Lam Hui, Austin Joyce, Riccardo Penco +2
We study the near-zone symmetries of a massless scalar field on four-dimensional black hole backgrounds. We provide a geometric understanding that unifies various recently discover…
Soft limits of the wavefunction in exceptional scalar theories
Noah Bittermann, Austin Joyce
We study the structure of the flat space wavefunctional in scalar field theories with nonlinearly realized symmetries. These symmetries imply soft theorems that are satisfied by wa…
An improved Noether's theorem for spacetime symmetries
Ioanna Kourkoulou, Alberto Nicolis, Guanhao Sun
We exploit an ambiguity somewhat hidden in Noether's theorem to derive systematically, for relativistic field theories, the stress-energy tensor's improvement terms that are associ…
