Kinematic space and the orbit method

Robert F. Penna, Claire Zukowski

Kinematic space has been defined as the space of codimension- spacelike extremal surfaces in anti de Sitter (AdS) spacetime which, by the Ryu-Takayanagi proposal, comput…

Shift Symmetries in (Anti) de Sitter Space

James Bonifacio, Kurt Hinterbichler, Austin Joyce +1

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…

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…

Casimir force variability in one-dimensional QED systems

Yu. Voronina, I. Komissarov, K. Sveshnikov

The Casimir force between two short-range charge sources, embedded in a background of one dimensional massive Dirac fermions, is explored by means of the original $\ln\text{[Wronsk…

Inflationary soft theorems revisited: A generalized consistency relation

Lam Hui, Austin Joyce, Sam S. C. Wong

We reconsider the derivation of soft theorems associated with nonlinearly-realized symmetries in cosmology. Utilizing the path integral, we derive a generalized consistency relatio…

Stable wormholes in scalar-tensor theories

Gabriele Franciolini, Lam Hui, Riccardo Penco +2

We reconsider the issue of whether scalar-tensor theories can admit stable wormhole configurations supported by a non-trivial radial profile for the scalar field. Using a recently…

Asymptotic symmetries of three dimensional gravity and the membrane paradigm

Mariana Carrillo-Gonzalez, Robert F. Penna

The asymptotic symmetry group of three-dimensional (anti) de Sitter space is the two dimensional conformal group with central charge . Usually the asymptotic charge alg…

Supersymmetric Partially Massless Fields and Non-Unitary Superconformal Representations

Sebastian Garcia-Saenz, Kurt Hinterbichler, Rachel A. Rosen

We find and classify the SUSY multiplets on AdS which contain partially massless fields. We do this by studying the non-unitary representations of the superc…

Effective Field Theory of Black Hole Quasinormal Modes in Scalar-Tensor Theories

Gabriele Franciolini, Lam Hui, Riccardo Penco +2

The final ringdown phase in a coalescence process is a valuable laboratory to test General Relativity and potentially constrain additional degrees of freedom in the gravitational s…

The dS swampland conjecture and the Higgs potential

Frederik Denef, Arthur Hebecker, Timm Wrase

According to a conjecture recently put forward in arXiv:1806.08362, the scalar potential of any consistent theory of quantum gravity satisfies a bound $|\nabla V|/V \geq {\cal…

Black Hole Mechanics for Massive Gravitons

Rachel A Rosen

It has been argued that black hole solutions become unavoidably time-dependent when the graviton has a mass. In this work we show that, if the apparent horizon of the black hole is…

A Geometric Construction of Solutions to 11D Supergravity

Teng Fei, Bin Guo, Duong H. Phong

Necessary and sufficient conditions are provided for a class of warped product manifolds with non-vanishing flux to be supersymmetric solutions of 11D supergravity. Many noncompact…

Conformal spacelike-timelike correspondence in QCD

Alfred H. Mueller

This paper is a study of a spacelike-timelike conformal correspondence in QCD. When the times at vertices are fixed in an A_+ = 0 gauge calculation the distribution of gluons in a…
