A one-world interpretation of quantum mechanics
Isaac Layton, Jonathan Oppenheim, Zachary Weller-Davies
The measurement problem is the issue of explaining how the objective classical world emerges from a quantum one. Here we take a different approach. We assume that there is an objec…
Path integrals for classical-quantum dynamics
Jonathan Oppenheim, Zachary Weller-Davies
Consistent dynamics which couples classical and quantum degrees of freedom exists. This dynamics is linear in the hybrid state, completely positive and trace preserving. Starting f…
A healthier semi-classical dynamics
Isaac Layton, Jonathan Oppenheim, Zachary Weller-Davies
We study the back-reaction of quantum systems onto classical ones. Taking the starting point that semi-classical physics should be described at all times by a point in classical ph…
Gravitationally induced decoherence vs space-time diffusion: testing the quantum nature of gravity
Jonathan Oppenheim, Carlo Sparaciari, Barbara Šoda +1
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 explor…
The two classes of hybrid classical-quantum dynamics
Jonathan Oppenheim, Carlo Sparaciari, Barbara Šoda +1
Coupling between quantum and classical systems is consistent, provided the evolution is linear in the state space, preserves the split of systems into quantum and classical degrees…
Objective trajectories in hybrid classical-quantum dynamics
Jonathan Oppenheim, Carlo Sparaciari, Barbara Šoda +1
Consistent dynamics which couples classical and quantum degrees of freedom exists, provided it is stochastic. This dynamics is linear in the hybrid state, completely positive and t…
