Classical Fluid Analogies for Schr\"odinger-Newton Systems
read the original abstract
The Schr\"odinger-Poisson formalism has found a number of applications in cosmology, particularly in describing the growth by gravitational instability of large-scale structure in a universe dominated by ultra-light scalar particles. Here we investigate the extent to which the behaviour of this and the more general case of a Schr\"odinger-Newton system, can be described in terms of classical fluid concepts such as viscosity and pressure. We also explore whether such systems can be described by a pseudo-Reynolds number as for classical viscous fluids. The conclusion we reach is that this is indeed possible, but with important restrictions to ensure physical consistency.

Entanglement generation in a two-body Schr\"odinger--Newton model
In the two-body Schrödinger-Newton model the nonlinear self-field leaves the Schmidt spectrum unchanged while the pair potential generates entanglement, with growth amplified by delocalized or asymmetric initial states.
