Alexander Franklin (King’s College London)
“Incoherent? No, Just Decoherent: How Quantum Many Worlds Emerge”
The modern Everett interpretation of quantum mechanics describes an emergent multiverse. The goal of this talk is to provide a perspicuous characterisation of how the multiverse emerges making use of a recent account of (weak) ontological emergence. This will be cashed out with a case study that identifies decoherence as the mechanism for emergence. The greater metaphysical clarity enables the rebuttal of critiques from Maudlin (2010), Monton (2013), and Dawid and Thébault (2015) that cast the emergent multiverse ontology as incoherent or empirically ungrounded.
