Abstract: I commented on three recent preprints about local equilibration of closed system: the fact the locally a system may appear at equilibrium even the global system is evolving under a unitary evolution. These are progress in a program initiated a long ago and “rediscovered” by Peter Reimann [1] and Noah Linden and collaborators [2]. I also showed some articles I found interesting in the last weeks.
