Finite temperature Functional RG, droplets and decaying Burgers Turbulence
– The functional RG (FRG) approach to pinning of d-dimensional manifolds is reexamined at any temperature T . A simple relation between the coupling function R(u) and a physical observable is shown in any d. In d = 0 its beta function is displayed to a high order, ambiguities resolved; for random field disorder (Sinai model) we obtain exactly the T = 0 fixed point R(u) as well as its thermal bo...
متن کاملScaling and Exotic Regimes in Decaying Burgers Turbulence
We analyze the stochastic scaling laws arising in the invicid limit of the decaying solutions of the Burgers equation. The linear scaling of the velocity structure functions is shown to reflect the domination by shocks of the long-time asymptotics. We exhibit new self-similar statistics of solutions describing phases with diluted shocks. Some speculations are included on the nature of systems w...
متن کاملSailing the Deep Blue Sea of Decaying Burgers Turbulence 0
We study Lagrangian trajectories and scalar transport statistics in decaying Burgers turbulence. We choose velocity fields solutions of the inviscid Burgers equation whose probability distributions are specified by Kida’s statistics. They are time-correlated, not time-reversal invariant and not Gaussian. We discuss in some details the effect of shocks on trajectories and transport equations. We...

متن کاملDensity Probability Distribution Functions in Supersonic Hydrodynamic and Mhd Turbulence
We study the probability distribution function (PDF) of the mass density in simulations of supersonic turbulence with properties appropriate for molecular clouds. For this study we use Athena, a new higher-order Godunov code. We find there are surprisingly similar relationships between the mean of the time-averaged PDF and the turbulent Mach number for driven hydrodynamic and strong-field MHD t...
