Gravitational Decoherence and Stochastic Tidal Phase Diffusion of Galactic Dark Matter Solitons: Microscopic Lindblad Evolution and Pulsar Timing Observables

Abstract: Wave or Fuzzy Dark Matter (ψ\psiψDM), consisting of ultralight bosons of mass ma∼10−22 eVm_a \sim 10^{-22}\text{ eV}ma∼10−22 eV, is conventionally modeled as an isolated, eternally coherent macroscopic Bose-Einstein condensate (τdecoh→∞\tau_{\text{decoh}} \to \inftyτdecoh→∞) governed by the unitary Gross-Pita...
