Causality and Locality Properties of MONDian Models of Dark Matter

Acausality in Superfluid Dark Matter and MOND-like Theories

We examine the causality and locality properties of the so-called superfluid dark matter models, in which a complex bosonic field undergoes spontaneous symmetry breaking on galactic scales, entering a superfluid phase with a 3/2 kinetic scaling in the low energy effective theory, that mediates a long-ranged mondian force.

We show that the high energy perturbations that violate global hyperbolicity of the equations of motion in the mond regime and can be superluminal in other parts of phase space.

We also examine a range of alternative models, finding that they also exhibit forms of non-locality.
