Removing the Cosmological Bound on the Axion Scale via Confinement During Inflation
Gia Dvali, Sophia Fitz, Lucy Komisel
We implement the scenario of early relaxation of the axion via a high scale confinement within grand unified theory and study an epoch of strong QCD in inflationary cosmolo…

Cosmic strings and domain walls of the QCD quark condensate with and without a hidden axion
Gia Dvali, Lucy Komisel, Anja Stuhlfauth
The chiral quark condensate of QCD, which spontaneously breaks the anomalous axial symmetry, gives rise to axionic type global string-wall systems. If a Peccei-Quinn type axion exi…
