We investigate the evolution of cosmic voids in the Schrodinger Poisson formalism, finding wave mechanical solutions for the dynamics in a standard cosmological background with appropriate boundary conditions. We compare the results in this model to those obtained using the Zel'dovich approximation. We discuss the advantages of studying voids in general and the advantages of the Schrodinger Poisson description over other approaches. In particular, emphasizing the utility of the free particle approximation. We also discuss a dimensionless number, similar to the Reynolds number, for this system which allows our void solutions to be scaled to systems of different physical dimensions.

  1. Why Cosmic Voids Matter: Pristine Evolution

    astro-ph.CO 2025-09 conditional novelty 7.0 of 10

    Cosmic voids traced by halos become stable at late times, and the matter around them evolves linearly, supporting their use as clean dark-energy probes.

  2. Classical Fluid Analogies for Schr\"odinger-Newton Systems

    astro-ph.CO 2025-07 conditional novelty 4.0 of 10

    The authors show that classical fluid analogies for Schrödinger-Newton systems are only consistent in a semi-classical limit and that a pseudo-Reynolds number can be defined for void dynamics.
