Most of what I read in the Everett context refers to a* theory*: https://plato.stanford.edu/entries/qm-everett/ : Hugh Everett III’s relative-state formulation of quantum mechanics is a proposal for solving the quantum measurement problem by dropping the collapse dynamics from the standard von Neumann-Dirac formulation of quantum mechanics. Everett intended to recapture the predictions of the standard collapse theory by explaining why observers nevertheless get determinate measurement records that satisfy the standard quantum statistics. There has been considerable disagreement over the precise content of his theory and how it was suppose to work. Here we will consider how Everett himself presented the *theory*, then briefly compare his presentation to the many-worlds interpretation and other no-collapse options. https://arxiv.org/abs/1801.08132 : Mad-Dog Everettianism: Quantum Mechanics at Its Most Minimal Sean M. Carroll <https://arxiv.org/search/quant-ph?searchtype=author&query=Carroll%2C+S+M>, Ashmeet Singh <https://arxiv.org/search/quant-ph?searchtype=author&query=Singh%2C+A> (Submitted on 23 Jan 2018) To the best of our current understanding, quantum mechanics is part of the most fundamental picture of the universe. It is natural to ask how pure and minimal this fundamental quantum description can be. The simplest quantum ontology is that of the Everett or Many-Worlds interpretation, based on a vector in Hilbert space and a Hamiltonian. Typically one also relies on some classical structure, such as space and local configuration variables within it, which then gets promoted to an algebra of preferred observables. We argue that even such an algebra is unnecessary, and the most basic description of the world is given by the spectrum of the Hamiltonian (a list of energy eigenvalues) and the components of some particular vector in Hilbert space. Everything else - including space and fields propagating on it - is emergent from these minimal elements. @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
