Query: An angular momentum based graviton detector   We show that gravitons with energy $E<\Omega$, where $\Omega$ is the energy
gap a localized non-relativistic system, can be detected by finite-time
interactions with a detector. Our detector is based on a quadrupole moment
interaction between the hydrogen atom and the gravitational field in the
linearized approximation. In this model, the external agent responsible for
switching the interaction on an off inputs energy into the system, which
creates a non-zero excitation probability even when the field is in the vacuum
state. However, when the gravitational field is in a one-particle state with
angular momentum, we obtain excitations due to the field's particle content.
These detector excitations are then associated with the detection of gravitons.
We also discuss a possible physical realization of our model where the
electromagnetic field plays the role of the external agent.
