It is demonstrated that the usually employed group average, used to dispense of the notion of an external reference frame, leads to unp

Jesus Gregorio Smith,Sally Brownn the space of solutions is introduced. The canonical quantization of this field theory is carried out, emphasizing the non-uniqueness of the vacuum state. The particle interpretation of such a field theory is described in detail with an emphasis on the importance of an operational definition of particles.

Randa Simpson Hovater,D. Nicole Farris. It is shown that the entanglement harvesting protocol depends sensitively on the global topology of these spacetimes, suggesting that the entanglement structure of a field theory is sensitive to the global spacetime topology in such a way that is in principle observable by detectors interacting locally with the field.
