# Observers and Locality in Everett Quantum Field Theory

@article{Rubin2009ObserversAL, title={Observers and Locality in Everett Quantum Field Theory}, author={Mark A. Rubin}, journal={Foundations of Physics}, year={2009}, volume={41}, pages={1236-1262} }

A model for measurement in collapse-free nonrelativistic fermionic quantum field theory is presented. In addition to local propagation and effectively-local interactions, the model incorporates explicit representations of localized observers, thus extending an earlier model of entanglement generation in Everett quantum field theory (Rubin in Found. Phys. 32:1495–1523, 2002). Transformations of the field operators from the Heisenberg picture to the Deutsch-Hayden picture, involving fictitious…

### Probability, preclusion and biological evolution in Heisenberg-picture Everett quantum mechanics

- Physics

Hard preclusion can provide an explanation for biological evolution, which can in turn explain their subjective experiences of, and reactions to, "ordinary" probabilistic phenomena, and the compatibility of those experiences and reactions with what the authors conventionally take to be objective probabilities arising from physical laws.

This work investigates the requirements for coarse grainings to yield decoherent sets of histories that are quasiclassical, i.e., such that the individual histories obey, with high probability, effective classical equations of motion interrupted continually by small fluctuations and occasionally by large ones.
