Query: From chaos to many-body localization: some introductory notes   Staring from the kicked rotator as a paradigm for a system exhibiting
classical chaos, we discuss the role of quantum coherence resulting in
dynamical localization in the kicked quantum rotator. In this context, the
disorder-induced Anderson localization is also discussed. Localization in
interacting, quantum many-body systems (many-body localization) may also occur
in the absence of disorder, and a practical way to identify its occurrence is
demonstrated for an interacting spin chain.
