Trapping Effect for QCD Axion Dark Matter

Shota Nakagawa, Fuminobu Takahashi, Masaki Yamada

In the early universe, the potential of a scalar field can be significantly modified, and the scalar field may be trapped for a long time in a different location than the current v…

Stochastic Axion Dark Matter in Axion Landscape

Shota Nakagawa, Fuminobu Takahashi, Wen Yin

We study the stochastic axion dark matter scenario in the axion landscape, where one of the axions is light and stable and therefore explains dark matter. If the axion mass at the…
