An important question is to understand what is special about maximally chaotic systems which saturate this bound. Here I will discuss a proposal for a `hydrodynamic&#8217; origin of chaos in such systems, and discuss hallmarks of maximally chaotic systems. In particular I will discuss how in maximally chaotic systems there is a suppression of exponential growth in commutator squares of generic few-body operators. This suppression appears to indicate that the nature of operator scrambling in maximally chaotic systems is fundamentally different to scrambling in non-maximally chaotic systems.<\/p>\n<\/div><\/div>\n\n\n<iframe loading=\"lazy\"  style=\"display: block; margin: 0px auto;\"  id=\"_ytid_29217\"  width=\"1170\" height=\"878\"  data-origwidth=\"1170\" data-origheight=\"878\" src=\"https:\/\/www.youtube.com\/embed\/ugdMj3YFX5A?enablejsapi=1&#038;autoplay=0&#038;cc_load_policy=0&#038;cc_lang_pref=&#038;iv_load_policy=1&#038;loop=0&#038;rel=1&#038;fs=1&#038;playsinline=0&#038;autohide=2&#038;theme=dark&#038;color=red&#038;controls=1&#038;\" class=\"__youtube_prefs__  no-lazyload\" title=\"YouTube player\"  allow=\"fullscreen; accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen data-no-lazy=\"1\" data-skipgform_ajax_framebjll=\"\"><\/iframe>","protected":false},"excerpt":{"rendered":"<p>Date : April 27, 2021, 16:00 CEST Mike Blake (University of Bristol) Link:&nbsp;https:\/\/zoom.us\/j\/98810153463?pwd=WWtWQXBURGw1NTZ2Rm82QThPbW42dz09 Title:&nbsp;On systems of maximal quantum chaos Abstract:\u00a0 A remarkable feature of chaos in many-body quantum systems is the existence of a bound on the quantum Lyapunov exponent.
