A bstract We construct stable and causal effective field theories (EFTs) for describing
statistical fluctuations in relativistic diffusion and relativistic hydrodynamics. These EFTs are …

This is an elementary set of lectures on generalized global symmetries originally given at the
Jena TPI School on QFT and Holography, designed to be accessible to the reader with a …

A bstract We construct a theory of hydrodynamic transport for systems with conserved dipole
moment, U (1) charge, energy, and momentum. These models have been considered in the …

We investigate the thermodynamics of equilibrium thermal states and their near-equilibrium
dynamics in systems with fractonic symmetries in arbitrary curved space. By explicitly …

We explore the physics of relativistic gapless phases defined by a mixed anomaly between
two generalized conserved currents. The gapless modes can be understood as Goldstone …

A bstract Higher-group symmetries are combinations of higher-form symmetries which
appear in various field theories. In this paper, we explain how higher-group symmetries …

We explore the necessary conditions for 1-form symmetries to emerge in the long-distance
limit when they are explicitly broken at short distances. A minimal requirement is that there …

A bstract We use the duality between gravitational dynamics and fluids living on dynamical
surfaces carrying multiple charges, known as the blackfold approach, to perturbatively …

A bstract We study the linear response of relativistic superfluids with a non-zero superfluid
velocity. For sufficiently large superflow, an instability develops via the crossing of a pole of …

A bstract We present a comprehensive study of hydrodynamic theories for superfluids with
dipole symmetry. Taking diffusion as an example, we systematically construct a …
