Tachyonic gravitational dark matter production after inflation

Giorgio Laverda, Javier Rubio, Tom\'as Mendes

A quadratic coupling to the Gauss-Bonnet invariant renders a spectator scalar tachyonic after inflation, producing the observed dark matter density.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We find that this purely gravitational mechanism can robustly reproduce the observed dark matter relic density over a wide range of masses and inflationary scales, providing also a simple fitting function that enables a lattice-independent application of our results.

C2weakest assumption

The spectator-field approximation, which assumes the dark matter scalar does not significantly back-react on the background spacetime evolution during the brief tachyonic phase.

C3one line summary

Tachyonic instabilities from post-inflation curvature reorganization via quadratic Gauss-Bonnet coupling produce the observed dark matter relic density across wide mass and scale ranges, backed by lattice simulations and a fitting function.
