Gravitationally trapped axions on Earth

Understand

We advocate for the idea that there is a fundamentally new mechanism for axion production on Earth, as recently suggested in Fischer et al.

• (2018) and Liang & Zhitnitsky (2018).
• We specifically focus on production of axions within Earth, with low velocities such that they will be trapped in the gravitational field.
• Our computations are based on the so-called Axion Quark Nugget (AQN) dark matter model, which was originally invented to explain the similarity of the dark and visible cosmological matter densities.
