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…

Partition functions on 3d circle bundles and their gravity duals

Chiara Toldo, Brian Willett

The partition function of a three-dimensional theory on the manifold , an bundle of degree over a closed Riemann surface , was re…

Higher Spin de Sitter Hilbert Space

Dionysios Anninos, Frederik Denef, Ruben Monten +1

We propose a complete microscopic definition of the Hilbert space of minimal higher spin de Sitter quantum gravity and its Hartle-Hawking vacuum state. The fundamental degrees of f…

Generalized surface tension bounds in vacuum decay

Ali Masoumi, Sonia Paban, Erick J. Weinberg

Coleman and De Luccia (CDL) showed that gravitational effects can prevent the decay by bubble nucleation of a Minkowski or AdS false vacuum. In their thin-wall approximation this h…

Systematics of Aligned Axions

Thomas C. Bachlechner, Kate Eckerle, Oliver Janssen +1

We describe a novel technique that renders theories of axions tractable, and more generally can be used to efficiently analyze a large class of periodic potentials of arbitrary…

A multipole-expanded effective field theory for vortex ring-sound interactions

Sebastian Garcia-Saenz, Ermis Mitsou, Alberto Nicolis

The low-energy dynamics of a zero temperature superfluid or of the compressional modes of an ordinary fluid can be described by a simple effective theory for a scalar field---the s…

invariant fluid dynamics at null infinity

Robert F. Penna

We revisit the boundary dynamics of asymptotically flat, three dimensional gravity. The boundary is governed by a momentum conservation equation and an energy conservation equation…

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…

Computational complexity of the landscape II - Cosmological considerations

Frederik Denef, Michael R. Douglas, Brian Greene +1

We propose a new approach for multiverse analysis based on computational complexity, which leads to a new family of "computational" measure factors. By defining a cosmology as a sp…

Mutual Interactions of Phonons, Rotons, and Gravity

Alberto Nicolis, Riccardo Penco

We introduce an effective point-particle action for generic particles living in a zero-temperature superfluid. This action describes the motion of the particles in the medium at eq…

Vortex precession in trapped superfluids from effective field theory

Angelo Esposito, Rafael Krichevsky, Alberto Nicolis

We apply a recently developed effective string theory for vortex lines to the case of two-dimensional trapped superfluids. We do not assume a perturbative microscopic description f…

Axions of Evil

Thomas C. Bachlechner, Kate Eckerle, Oliver Janssen +1

We provide a systematic framework for theories of multiple axions. We discover a novel type of "alignment" that renders even very complex theories analytically tractable. Theories…

Near-horizon BMS symmetries as fluid symmetries

Robert F. Penna

The Bondi-van der Burg-Metzner-Sachs (BMS) group is the asymptotic symmetry group of asymptotically flat gravity. Recently, Donnay et al. have derived an analogous symmetry group a…

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…

Quantum q-Langlands Correspondence

Mina Aganagic, Edward Frenkel, Andrei Okounkov

We formulate a two-parameter generalization of the geometric Langlands correspondence, which we prove for all simply-laced Lie algebras. It identifies the q-conformal blocks of the…
