Universality Conjectures for Activated Random Walk
Lionel Levine, Cornell University
Monday, June 26, 2023
Abstract: Activated Random Walk is a particle system displaying avalanches on all scales. How universal are these avalanches? I’ll narrate five interlocking conjectures aimed at different aspects of this question: infinite-volume limits, cutoff, incompressibility, rotational symmetry, and hyperuniformity. Joint work with Feng Liang and with Vittoria Silvestri.
