# Can the wave function in configuration space be replaced by single-particle wave functions in physical space?

@article{Norsen2014CanTW, title={Can the wave function in configuration space be replaced by single-particle wave functions in physical space?}, author={Travis Norsen and Damiano Marian and Xavier Oriols}, journal={Synthese}, year={2014}, volume={192}, pages={3125-3151} }

The ontology of Bohmian mechanics includes both the universal wave function (living in 3N-dimensional configuration space) and particles (living in ordinary 3-dimensional physical space). Proposals for understanding the physical significance of the wave function in this theory have included the idea of regarding it as a physically-real field in its 3N-dimensional space, as well as the idea of regarding it as a law of nature. Here we introduce and explore a third possibility in which the…
