Anomaly and Brownian fluid particle in Navier-Stokes turbulence
Timo Aukusti Laine
We investigate the Navier-Stokes turbulence driven by a stochastic random Gaussian force. Using a field-theoretic approach, we uncover an anomaly that brings hidden structure to th…

Local symmetries, anomalies and constrains in Burgers Turbulence
Timo Aukusti Laine
We study stochastic Burgers turbulence without pressure. We first show that the variational derivative of the Burgers equation is dependent on the velocity field, suggesting the ex…

Symmetries of the Burgers Turbulence without Pressure
Timo Aukusti Laine
We investigate local symmetries of the Burgers turbulence driven by an external random force. By using a path integral formalism, we show that the Jacobian has physics in it; local…
