Damping of pseudo-Goldstone fields
Approximate symmetries abound in nature. If these symmetries are also spontaneously
broken, the would-be Goldstone modes acquire a small mass, or inverse correlation length …

Holography and magnetohydrodynamics with dynamical gauge fields
A bstract Within the framework of holography, the Einstein-Maxwell action with Dirichlet
boundary conditions corresponds to a dual conformal field theory in presence of an external …

Approximate symmetries, pseudo-Goldstones, and the second law of thermodynamics
We propose a general hydrodynamic framework for systems with spontaneously broken
approximate symmetries. The second law of thermodynamics naturally results in relaxation …

Anomaly obstructions to symmetry preserving gapped phases
Anomalies are renormalization group invariants that constrain the dynamics of quantum field
theories. We show that certain anomalies for discrete global symmetries imply that the …

Bound of diffusion constants from pole-skipping points: spontaneous symmetry breaking and magnetic field
A bstract We investigate the properties of pole-skipping of the sound channel in which the
translational symmetry is broken explicitly or spontaneously. For this purpose, we analyze, in …

Deformations, relaxation, and broken symmetries in liquids, solids, and glasses: A unified topological field theory
We combine hydrodynamic and field theoretic methods to develop a general theory of
phonons as Goldstone bosons in crystals, glasses, and liquids based on nonaffine …

Superfluids as higher-form anomalies
LV Delacrétaz, DM Hofman, G Mathys - SciPost Physics, 2020 - scipost.org
We recast superfluid hydrodynamics as the hydrodynamic theory of a system with an
emergent anomalous higher-form symmetry. The higher-form charge counts the winding …

Emergent generalized symmetries in ordered phases
SD Pace - arXiv preprint arXiv:2308.05730, 2023 - arxiv.org
We explore the rich landscape of higher-form and non-invertible symmetries that emerge at
low energies in generic ordered phases. Using that their charge is carried by homotopy …
