Subsystems (in)dependence in GIE proposals
Nicolas Boulle, Guilherme Franzmann
Recent proposals suggest that detecting entanglement between two spatially superposed masses would establish the quantum nature of gravity. However, these gravitationally induced e…
On the emergence of preferred structures in quantum theory
Antoine Soulas, Guilherme Franzmann, Andrea Di Biagio
We assess the possibilities offered by Hilbert space fundamentalism, an attitude towards quantum physics according to which all physical structures (e.g. subsystems, locality, spac…
Realism and Ontology in Quantum Mechanics and String Theory
Richard Dawid, Guilherme Franzmann
Dualities in physics have challenged traditional forms of scientific realism by undermining the idea that theories describe a unique underlying ontology. In this paper, we develop…
To be or not to be, but where?
Guilherme Franzmann
The identification of physical subsystems in quantum mechanics as compared to classical mechanics poses significant conceptual challenges, especially in the context of quantum grav…
