Fixing semi-classical physics from first principles: how to derive effective classical-quantum dynamics from open quantum theory
Isaac Layton
Semi-classical approaches approximate fully quantum descriptions with partially classical ones. Here we use a toy model to highlight the failings of the standard mean-field semi-cl…
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…
Restoring the second law to classical-quantum dynamics
Isaac Layton, Harry J. D. Miller
All physical theories should obey the second law of thermodynamics. However, existing proposals to describe the dynamics of hybrid classical-quantum systems either violate the seco…
The classical-quantum limit
Isaac Layton, Jonathan Oppenheim
The standard notion of a classical limit, represented schematically by , provides a method for approximating a quantum system by a classical one. In this work w…
