Euler-scale dynamical correlations in integrable systems with fluid motion

Understand

We devise an iterative scheme for numerically calculating dynamical two-point correlation functions in integrable many-body systems, in the Eulerian scaling limit.

• Expressions for these were originally derived in Ref.
• [1] by combining the fluctuation-dissipation principle with generalized hydrodynamics.
• Crucially, the scheme is able to address non-stationary, inhomogeneous situations, when motion occurs at the Euler-scale of hydrodynamics.
