A quantum oscillator interacting with a classical oscillator
Muhammad Sajjad, Andrea Russo, Maite Arcos +2
We study a quantum oscillator interacting with, and back-reacting on, a classical oscillator. This can be done consistently provided the quantum system decoheres, while the backrea…
Anomalous contribution to galactic rotation curves due to stochastic spacetime
Jonathan Oppenheim, Andrea Russo
We consider a proposed alternative to quantum gravity, in which the spacetime metric is treated as classical, even while matter fields remain quantum. Consistency of the theory nec…
Renormalisation of postquantum-classical gravity
Andrzej Grudka, Tim R. Morris, Jonathan Oppenheim +2
One of the obstacles to reconciling quantum theory with general relativity, is constructing a theory which is both consistent with observation, and and gives finite answers at high…
Diffeomorphism invariant classical-quantum path integrals for Nordstrom gravity
Jonathan Oppenheim, Andrea Russo, Zachary Weller-Davies
When classical degrees of freedom and quantum degrees of freedom are consistently coupled, the former diffuse, while the latter undergo decoherence. Here, we construct a theory of…
