Separation of time-scales in drift-diffusion equations on $\mathbb{R}^2$
Authors establish enhanced dissipation and separation of time-scales for a radially symmetric linear drift-diffusion problem on R^2, with the fast mixing time-scale depending only on the flow near the origin for power-law cases, via hypocoercivity.
