On the Aharonov-Bohm Effect and Why Heisenberg Captures Nonlocality Better Than Schr\"odinger

Abstract

I discuss in detail the history of the Aharonov-Bohm effect in Bristol and my encounters with Akira Tonomura later on. I then propose an idea that developed following the publication of the Aharonov-Bohm effect, namely the importance of modulo momentum and Heisenberg representation in dealing with non-local quantum phenomena.
