Characterizing stochastic inertia: when does noise increase escape times?
Robin Chemnitz, Maximilian Engel, Péter Koltai
Motivated by observations in atmospheric modelling, we investigate the effect of ``stochastic inertia'': in certain dynamical systems, small noise induces trajectories to stay long…

Mixing at the Batchelor Scale for White-In-Time Flows
Robin Chemnitz, Dennis Chemnitz
We consider the mixing properties of solutions to the advection-diffusion equation of a white-in-time velocity field on the 2-dimensional torus with four forced modes. As the diffu…
