Singularities in any physical theory are either remarkable indicators of the unknown
underlying fundamental theory, or indicate a change in the description of the physical reality …

The traditional view from particle physics is that quantum-gravity effects should become
detectable only at extremely high energies and small length scales. Owing to the significant …

We argue that if the Newtonian gravitational field of a body can mediate entanglement with
another body, then it should also be possible for the body producing the Newtonian field to …

We revisit a question asked by Dyson:“Is a graviton detectable?” We demonstrate that in
both Dyson's original sense and in a more modern measurement-theoretic sense, it is …

Gravity is the weakest of all known fundamental forces and poses some of the most
important open questions to modern physics: it remains resistant to unification within the …

This paper points out the importance of the quantum nature of the gravitational interaction
with matter in a linearized theory of quantum gravity induced entanglement of masses. We …

Recent advances in cooling, control, and measurement of mechanical systems in the
quantum regime have opened the possibility of the first direct observation of quantum …

We describe a variety of searches for new physics beyond the standard model of particle
physics which may be enabled in the coming years by the use of optically levitated masses …

This paper points out the importance of the assumption of locality of physical interactions,
and the concomitant necessity of propagation of an entity (in this case, off-shell quanta …

We consider two interacting systems when one is treated classically while the other system
remains quantum. Consistent dynamics of this coupling has been shown to exist, and …
