John Wheeler and Quantum Gravity

John Wheeler was the inventor of quantum gravity – not as a formal program for uniting general relativity and quantum mechanics, but as the potential key to a theory of everything. In this talk, I will show how he first imbued quantum gravity with this new role in the 1950s and then how (and why) …

Interference in quantum field theory: detecting ghosts with phases

I intend to discuss the implications of the principle of locality for interference in quantum field theory. As an example, I will consider the interaction of two charges via a mediating quantum field and the resulting interference pattern, in the Lorenz gauge. Using the Heisenberg picture, I will claim that detecting relative phases or entanglement between …
