*Abstract:*

A few days ago a paper by Curt von Keyserlingk, Frank Pollmann and Tibor Rakovszky appeared in which they give strong evidence that the time evolution of few-body correlators can be calculated efficiently classically in ergodic systems. The reason is that operator backflow from many-body operators to few-body correlators is exponentially suppressed in operator length. I think the result is both surprising from some angles and expected from others. I would be interested in working on this more and would appreciate a lively discussion after I introduced the papers.

We meet at 11h in the Theory seminar room starting with an informal
discussion, the talk begins at 11:20. Please don't forget to do a corona self test before.
