Linking thermodynamic variables like temperature T and the measure of chaos, the Lyapunov exponents λ, is a question of fundamental importance in many-body systems. By using nonlinear fluid equations in one and three dimensions, we show that in thermalized flows λ∝sqrt[T], in agreement with results from frustrated spin systems. This suggests an underlying universality and provides evidence for recent conjectures on the thermal scaling of λ. We also reconcile seemingly disparate effects…

Lagrangian manifestation of anomalies in active turbulence
We show that Lagrangian measurements in active turbulence bear imprints of turbulent and anomalous streaky hydrodynamics leading to a self-selection of persistent trajectories—Lévy walks— over
Dissipation-Range Fluid Turbulence and Thermal Noise
We revisit the issue of whether thermal fluctuations are relevant for incompressible fluid turbulence, and estimate the scale at which they become important. As anticipated by Betchov in a prescient
Many-body chaos and anomalous diffusion across thermal phase transitions in two dimensions
Chaos is an important characterization of classical dynamical systems. How is chaos linked to the long-time dynamics of collective modes across phases and phase transitions? We address this by

Temperature Dependence of the Butterfly Effect in a Classical Many-Body System.
TLDR
The full temperature dependence of two complementary aspects of the butterfly effect are determined: the Lyapunov exponent, μ, and the butterfly speed, v_{b}, and it is found that they all exhibit power-law behavior at low temperature, consistent with scaling of the form D∼v_{b}^{2}/μ and τ^{-1}∼T.

We study chaos in a classical limit of the Sachdev-Ye-Kitaev (SYK) model obtained in a suitably defined large-S limit. The low-temperature Lyapunov exponent is found to depend linearly on
