Hydrodynamic noise in one dimension: projected Kubo formula and how it vanishes in integrable models
Benjamin Doyon
Hydrodynamic noise is the Gaussian process that emerges at larges scales of space and time in many-body systems. It is justified by the central limit theorem, and represents degree…
Diffusive hydrodynamics of hard rods from microscopics
Friedrich Hübner, Leonardo Biagetti, Jacopo De Nardis +1
We derive exact equations governing the large-scale dynamics of hard rods, including diffusive effects that go beyond ballistic transport. Diffusive corrections are the first-order…
Circuits as a simple platform for the emergence of hydrodynamics in deterministic chaotic many-body systems
Sun Woo P. Kim, Friedrich Hübner, Juan P. Garrahan +1
The emergence of hydrodynamics is one of the deepest phenomena in many-body systems. Arguably, the hydrodynamic equations are also the most important tools for predicting large-sca…
Existence and Uniqueness of Solutions to the Generalized Hydrodynamics Equation
Friedrich Hübner, Benjamin Doyon
The generalized hydrodynamics (GHD) equation is the equivalent of the Euler equations of hydrodynamics for integrable models. Systems of hyperbolic equations such as the Euler equa…
