Gravity-induced entanglement under constrained dynamics
Hollis Williams
Tests of gravity-induced entanglement have been proposed as a route to probing the quantum nature of gravity, but existing schemes rely on free-fall interferometry of massive spati…
Entanglement Before Spacetime in Quantum-Gravity-Induced Interactions
Hollis Williams
Quantum-gravity-induced entanglement of massive systems (QGEM) is commonly approximated in the nonrelativistic static limit by a Newtonian interaction between spatially separated m…
Post-Newtonian Constraints on Semiclassical Gravity with Quantum Superpositions
Hollis Williams
Semiclassical gravity, in which a classical spacetime is sourced by the quantum expectation value of the stress-energy tensor, is a standard framework for describing the gravitatio…
Lorentz-violating pseudovectors in effective field theories for quantum gravity
Hollis Williams
Effective field theories which describe the coupling between gravity and matter fields have recently been extended to include terms with operators of non-minimal mass dimension. Th…
