Sign-Flipping Axion Potentials via Kapitza-Type Modulation by Heavy Axions

Kai Murai, Fuminobu Takahashi, Kosei Tomiyama

We show that the potential of a light axion can flip sign, or even nearly vanish, as a result of coherent oscillations of a heavier axion with which it mixes. This phenomenon is an…
