The QCD axion is a leading dark matter candidate that emerges as part of the solution to the strong CP problem in the Standard Model. The coupling of the axion to photons is the most common experimental probe, but much parameter space remains unexplored. The coupling of the QCD axion to the Standard Model scales linearly with the axion mass; therefore, the highly-motivated region 0.4-120 neV, corresponding to a GUT-scale axion, is particularly difficult to reach. This paper presents the design requirements for a definitive search for GUT-scale axions and reviews the technological advances needed to enable this program.

Dark Matter Nuclear Magnetic Resonance is Sensitive to Dark Photons and the Axion-Photon Coupling
CASPEr-Gradient, an NMR axion search, could simultaneously probe dark photon kinetic mixing to about 3e-16 and axion-photon coupling to about 2e-16 GeV^-1 near a mass of 1 micro-eV.

String Theory and Grand Unification Suggest a Sub-Microelectronvolt QCD Axion
String-theoretic axions consistent with grand unification and proton decay are predicted to have masses in the 3e-11 to 1e-8 eV window, with at most 47 axions in the Kreuzer-Skarke ensemble.

Five dimensional $SU(5) \times U(1)_{\rm PQ}$ grand unification
The authors propose a 5D SU(5) x U(1)_PQ orbifold model in which SU(5) breaking and a high-quality QCD axion from the fifth component of the U(1) field arise from the same boundary conditions, with intermediate-scale ...
