In F-theory GUTs, non-universal ALPs induced by hypercharge flux satisfy g_aγ/m_a well below the QCD axion prediction when gauge couplings unify near the string scale.

Tensor perturbations from FOPT and domain-wall sources are claimed to induce second-order scalar perturbations large enough to form primordial black holes, potentially all of the dark matter.
CMB polarization rotation can arise as a frequency-independent Pancharatnam phase when photons cross dark-sector vacuum interfaces, with no ultralight axion required.
