In Quantum Theory > s.a. time in quantum theory; modified quantum theories [time symmetric].
* Idea: The standard formalism rules out the existence of an arrow of time because it is based on conserved probabilities; The Brussels school proposed formalism based on the presence of resonances and the use of rigged Hilbert space and time-evolution semigroups; Or one can try quantum field theory.
* And observation: An experiment on entropy production in a microscopic nuclear-spin system indicates role of quantum correlations.
