We investigate the coupled dynamics of charge and energy in interacting lattice models with dipole conservation. We formulate a generic hydrodynamic theory for this combination of fractonic constraints and numerically verify its applicability to the late-time dynamics of a specific bosonic quantum system by developing a microscopic non-equilibrium quantum field theory. Employing a self-consistent 1 /N approximation in the number of field components, we extract all entries of a generalized diffusion…

Fracton hydrodynamics without time-reversal symmetry
We present an effective field theory for the nonlinear fluctuating hydrodynamics of a single conserved charge with or without time-reversal symmetry, based on the Martin-Siggia-Rose formalism. Applying

Fracton hydrodynamics
We introduce new classes of hydrodynamic theories inspired by the recently discovered fracton phases of quantum matter. Fracton phases are characterized by elementary excitations (fractons) with
Far-from-equilibrium dynamics of an ultracold Fermi gas
Nonequilibrium dynamics of an $\mathcal{N}$-fold spin-degenerate ultracold Fermi gas is described in terms of beyond-mean-field Kadanoff–Baym equations for correlation functions. Using a

Infinite families of fracton fluids with momentum conservation
We construct infinite families of new universality classes of fracton hydrodynamics with momentum conservation, both with multipole conservation laws and/or subsystem symmetry. We explore the effects
Quantum gas microscopy of Kardar-Parisi-Zhang superdiffusion
The Kardar-Parisi-Zhang (KPZ) universality class describes the coarse-grained behavior of a wealth of classical stochastic models. Surprisingly, KPZ universality was recently conjectured to also
Observing emergent hydrodynamics in a long-range quantum magnet
Identifying universal properties of nonequilibrium quantum states is a major challenge in modern physics. A fascinating prediction is that classical hydrodynamics emerges universally in the evolution

Critically Slow Operator Dynamics in Constrained Many-Body Systems.
The far-from-equilibrium dynamics of generic interacting quantum systems is characterized by a handful of universal guiding principles, among them the ballistic spreading of initially local
