A Critical Drift-Diffusion Equation: Intermittent Behavior via Geometric Brownian Motion on $SL (n)$

Peter S. Morfe, Felix Otto, Christian Wagner

This paper concerns the so-called diffusion in the curl of the 2d Gaussian free field, and its generalization to higher dimensions $n \geq 2$ , building on the scale-by-scale homoge…

On minimizing curves in a Brownian potential

Felix Otto, Matteo Palmieri, Christian Wagner

We study a $(1 + 1)$ -dimensional semi-discrete random variational problem that can be interpreted as the geometrically linearized version of the critical $2$ -dimensional random field…
