    "abstract": "We discuss a generalized quantum microcanonical ensemble. It describes\nisolated systems that are not necessarily in an eigenstate of the Hamilton\noperator. Statistical averages are obtained by a combination of a time average\nand a maximum entropy argument to resolve the lack of knowledge about initial\nconditions. As a result, statistical averages of linear observables coincide\nwith values obtained in the canonical ensemble. Non-canonical averages can be\nobtained by taking into account conserved quantities which are non-linear\nfunctions of the microstate.",
