The correlation structure of the drift det ermines the strength of the diffusion and there is a critical threshold\, bordering the diffusive and superdiffusive regimes. Physicists have long e xpected logarithmic-type superdiffusivity at this threshold\, and recently some progress in this direction has been made by mathematicians.\n\nI wil l discuss joint work with Scott Armstrong and Tuomo Kuusi in which we iden tify and obtain the sharp rate of superdiffusivity. We also establish a qu enched invariance principle under this scaling. Our proof is a quantitativ e renormalization group argument made rigorous by ideas from stochastic ho mogenization.\n\nZoom link: https://mcgill.zoom.us/j/88913958273?pwd=cDBIW GF3bmZSUmRzMFdLNGR3V2FXUT09\n DTSTART:20240328T153000Z DTEND:20240328T163000Z LOCATION:Room 920\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Ahmed Bou Rabee (NYU) URL:/mathstat/channels/event/ahmed-bou-rabee-nyu-35634 8 END:VEVENT END:VCALENDAR
