The Gaussian free-field as a stream function: asymptotics of effective diffusivity in infra-red cut-off

Georgiana Chatzigeorgiou, Peter Morfe, Felix Otto +1

We analyze the large-time asymptotics of a passive tracer with drift equal to the curl of the Gaussian free field in two dimensions with ultra-violet cut-off at scale unity. We pro…
