The coset construction for non-equilibrium systems

Michael J. Landry

We propose a systematic coset construction of non-equilibrium effective field theories (EFTs) governing the long-distance and late-time dynamics of relativistic, finite-temperature…

GLSM for Calabi-Yau Manifolds of Berglund-Hubsch Type

Konstantin Aleshkin, Alexander Belavin

In this note we briefly present the results of our computation of special Kähler geometry for polynomial deformations of Berglund-Hübsch type Calabi-Yau manifolds. We also build mi…

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…

The Cosmological Bootstrap: Weight-Shifting Operators and Scalar Seeds

Daniel Baumann, Carlos Duaso Pueyo, Austin Joyce +2

A key insight of the bootstrap approach to cosmological correlations is the fact that all correlators of slow-roll inflation can be reduced to a unique building block---the four-po…

Poincaré Constraints on Celestial Amplitudes

Y. T. Albert Law, Michael Zlotnikov

The functional structure of celestial amplitudes as constrained by Poincaré symmetry is investigated in and -point cases for massless external particles of various spin,…

Shift-Symmetric Spin-1 Theories

James Bonifacio, Kurt Hinterbichler, Laura A. Johnson +1

We study interacting massive spin-1 theories in de Sitter (dS) and anti-de Sitter (AdS) space that possess shift symmetries parametrized by (A)dS Killing vectors. We show how they…

Classical Glasses, Black Holes, and Strange Quantum Liquids

Davide Facoetti, Giulio Biroli, Jorge Kurchan +1

From the dynamics of a broad class of classical mean-field glass models one may obtain a quantum model with finite zero-temperature entropy, a quantum transition at zero temperatur…

Celestial Amplitudes: Conformal Partial Waves and Soft Limits

Dhritiman Nandan, Anders Schreiber, Anastasia Volovich +1

Massless scattering amplitudes in four-dimensional Minkowski spacetime can be Mellin transformed to correlation functions on the celestial sphere at null infinity called celestial…

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…
