EPJ H - Foundations of Quantum Statistical Physics Revisited

There is a divide, in quantum statistical physics, between the "ensemblists" who regard thermal equilibrium as a property of an ensemble (or a mixed state) and the "individualists" who regard thermal equilibrium as a property of an individual system (in a pure state). A long forgotten concept of equilibrium put forward by John von Neumann in 1929 is reanalyzed and shown to be influenced by both approaches, yet to be mainly based on the individualist view - a view that has gained ground recently.
