Adiabatic suppression of the axion abundance and isocurvature due to coupling to hidden monopoles

Abstract The string theory predicts many light fields called moduli and axions, which cause a cosmological problem due to the overproduction of their coherent oscillation after inflation. One of the prominent solutions is an adiabatic suppression mechanism, which, however, is non-trivial to achieve...
