A scaling non-compact QCD axion
Georgios K. Karananas, Mikhail Shaposhnikov
We present a dynamical mechanism for the erasure of inflationary isocurvature perturbations of the non-compact QCD axion. The key ingredient is an early-time runaway exponential po…

QCD axion from broken scale symmetry
Georgios K. Karananas, Mikhail Shaposhnikov
A consistent non-compact axion cosmology requires a non-periodic field, an effective field theory valid sufficiently above the inflationary scale, and a small non-QCD contribution…

Three-form lifting of dilaton flat direction without and with gravity
Georgios K. Karananas
Spontaneous scale symmetry breaking is commonly associated with a flat direction in the action. We show that this need not be so if the dilaton is coupled to a three-form field in…
