Motivated in part by the black hole information paradox, but also by a general attempt to consider possible modifications to standard field theory, we examine evolution laws in which pure states evolve to mixed states. Such theories have been previously rejected because of a tension between locality and conservation laws. Here we show that this tension can be resolved in a relational framework. We also discuss possible ways to couple this theory to gravity, and a generalisation of Noether’s theorem.
