Thermal Positivity
Clifford Cheung, Rachel A. Rosen
We argue that Lorentz invariance and unitarity impose sharp constraints on thermodynamic quantities. By relating thermal vacuum diagrams to forward scattering amplitudes, we derive…
On Entropy Bounds for Irrelevant Operators
Lucas Fernández-Sarmiento, Riccardo Penco, Rachel A Rosen
Consistency constraints for low-energy theories, especially those lacking Lorentz invariance, have recently garnered attention. Building on results from black hole thermodynamics,…
Applications of de Sitter Causality Conditions
Daniel McLoughlin, Rachel A Rosen
We find explicit de Sitter shockwave solutions in arbitrary spacetime dimensions. We use these to determine the dimensional-dependent "stretching" of the de Sitter Penrose diagram…
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…
Gravitational Collapse in Massive Gravity on de Sitter Spacetime
Roman Berens, Luke Krauth, Rachel A. Rosen
We analyze the evolution of a homogenous and pressureless ball of dust (or "star") in ghost-free massive gravity on de Sitter spacetime. We find that gravitational collapse does no…
Supersymmetric Partially Massless Fields and Non-Unitary Superconformal Representations
Noah Bittermann, Sebastian Garcia-Saenz, Kurt Hinterbichler +1
We find and classify the simplest SUSY multiplets on AdS which contain partially massless fields. We do this by studying representations of the , …
Black hole perturbations of massive and partially massless spin-2 fields in (anti) de Sitter spacetime
Rachel A. Rosen, Luca Santoni
We provide a systematic and comprehensive derivation of the linearized dynamics of massive and partially massless spin-2 particles in a Schwarzschild (anti) de Sitter black hole ba…
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…
Constraints on a Gravitational Higgs Mechanism
James Bonifacio, Kurt Hinterbichler, Rachel A. Rosen
We show that it is impossible to improve the high-energy behavior of the tree-level four-point amplitude of a massive spin-2 particle by including the exchange of any number of sca…
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…
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…
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…
Eikonal Scattering and Asymptotic Superluminality of Massless Higher Spin Fields
Kurt Hinterbichler, Austin Joyce, Rachel A. Rosen
We consider scattering of massless higher-spin particles in the eikonal regime in four dimensions. By demanding the absence of asymptotic superluminality, corresponding to positivi…
Massive and Massless Spin-2 Scattering and Asymptotic Superluminality
James Bonifacio, Kurt Hinterbichler, Austin Joyce +1
We constrain theories of a massive spin-2 particle coupled to a massless spin-2 particle by demanding the absence of a time advance in eikonal scattering. This is an -matrix con…
Massive Spin-2 Scattering and Asymptotic Superluminality
Kurt Hinterbichler, Austin Joyce, Rachel A. Rosen
We place model-independent constraints on theories of massive spin-2 particles by considering the positivity of the phase shift in eikonal scattering. The phase shift is an asympto…
Non-Singular Black Holes in Massive Gravity: Time-Dependent Solutions
Rachel A Rosen
When starting with a static, spherically-symmetric ansatz, there are two types of black hole solutions in dRGT massive gravity: (i) exact Schwarzschild solutions which exhibit no Y…
Positivity Constraints for Pseudo-linear Massive Spin-2 and Vector Galileons
James Bonifacio, Kurt Hinterbichler, Rachel A. Rosen
We derive analyticity constraints on a nonlinear ghost-free effective theory of a massive spin-2 particle known as pseudo-linear massive gravity, and on a generalized theory of a m…
No-go for Partially Massless Spin-2 Yang-Mills
Sebastian Garcia-Saenz, Kurt Hinterbichler, Austin Joyce +2
There are various no-go results forbidding self-interactions for a single partially massless spin-2 field. Given the photon-like structure of the linear partially massless field, i…
Partially Massless Monopoles and Charges
Kurt Hinterbichler, Rachel A. Rosen
Massive higher spin fields on de Sitter space exhibit enhanced gauge symmetries at special values of the mass. These fields are known as "partially massless." We study the structur…
A Note on Ghost-Free Matter Couplings in Massive Gravity and Multi-Gravity
Kurt Hinterbichler, Rachel A. Rosen
We consider a recently proposed non-minimal matter coupling in massive gravity and multi-gravity. We argue that, when formulated in terms of unconstrained vielbeins, this matter co…
A non-linear extension of the spin-2 partially massless symmetry
Sebastian Garcia-Saenz, Rachel A. Rosen
We investigate the possibility of extending the "partially massless" symmetry of a spin-2 field in de Sitter to nonlinear order. To do so, we impose a closure condition on the symm…
Wess-Zumino Terms for Relativistic Fluids, Superfluids, Solids, and Supersolids
Luca V. Delacrétaz, Alberto Nicolis, Riccardo Penco +1
We use the coset construction of low-energy effective actions to systematically derive Wess-Zumino (WZ) terms for fluid and isotropic solid systems in two, three and four spacetime…

Alberto Nicolis, Riccardo Penco, Rachel A. Rosen
We provide a systematic coset construction of the effective field theories governing the low-energy dynamics of relativistic fluids and solids, and of their "super" counterparts. T…
More on gapped Goldstones at finite density: More gapped Goldstones
Alberto Nicolis, Riccardo Penco, Federico Piazza +1
It was recently argued that certain relativistic theories at finite density can exhibit an unconventional spectrum of Goldstone excitations, with gapped Goldstones whose gap is exa…
