abstract
We present a new mechanism to generate a coherently oscillating dark vector field from axion-SU(2) gauge field dynamics during inflation. The SU(2) gauge field acquires a nonzero background sourced by an axion during inflation, and it acquires a mass through spontaneous symmetry breaking after inflation. We find that the coherent oscillation of the dark vector field can account for dark matter in the mass range of $10^{-13}-1$ eV in a minimal setup. In a more involved scenario, the range can be wider down to the fuzzy dark matter region. One of the dark vector fields can be identified as the dark photon, in which case this mechanism evades the notorious constraints for isocurvature perturbation, statistical anisotropy, and the absence of ghosts that exist in the usual misalignment production scenarios. Phenomenological implications are discussed.

Misalignment production of isotropized vector dark matter?
Kinetic-coupling misalignment of an isotropized multi-vector condensate cannot produce dark matter: non-Gaussianity and isocurvature constraints exclude the viable parameter space in both weak- and strong-mixing regimes.

Deep Reinforcement Learning Based Routing for Heterogeneous Multi-Hop Wireless Networks
A DQN routing scheme with channel-based neighbor selection is claimed to match optimal end-to-end rates, but the full text is about dark photon searches, not wireless routing.
