Abstract
Zoom link: https://cam-ac-uk.zoom.us/j/88472852021?pwd=Tnd4aY6KAlPWwxCw0m6JRp6AVEBK1s.1
I will discuss dynamics of magnetization transfer (or in general, transfer of a conserved charge) between bi-partition of an infinite (or large) spin lattice system, either classical or quantum.
We conjecture that for integrable interacting dynamics the scaling of cummulants is anomalous – critical, in the sense that the growth exponents depend on the order of the cumulants. We illustrate the finding by numerical simulations of classical Landau Lifshitz and numerical/quantum simulations of Heisenberg spin chain, as well as a simple exactly solvable model of charged deterministic cellular automaton.
