Abstract
Charged particles influenced by electromagnetic fields, even when the two never touch?
Surely, it can only be quantum physics. But surprisingly, the quantum nature of this
particular effect has been disputed.
In the phenomenon known as the Aharonov-Bohm effect, magnetic forces seem to act on
charged particles such as electrons even though the particles do not cross any magnetic
field lines. Is this evidence for electromagnetic forces that work in new and unsuspected
ways? Or is it just that infamous source of Albert Einstein's discomfort - quantummechanical 'spooky action at a distance'? In the latest chapter in an involved history,
detailed in Physical Review Letters, Caprez et al.(see link below) provide convincing
evidence for the second of these options: that the Aharonov-Bohm effect is purely
quantum mechanical in origin.

3. We started to work in december 2008 on preparing the material for the movie shot by
the Perimeter Institute of Theoretical Physics in our lab. This movie is being made for
high school teachers and students.
