Sound Speed Resonance: A Novel Mechanism of Matter-Graviton Conversation
The matter-to-graviton conversion and the graviton-to-matter conversion can be realized by the oscillatory sound speed of the graviton and the matter fields respectively. This mechanism is in fact quite general. It can occur in a large class of theories, including the Einstein gravity minimally coupled with the standard model in particle physics, the Horndeski theory, and the theories beyond Horndeski.
