Aharonov-Bohm superselection sectors
Claudio Dappiaggi, Giuseppe Ruzzi, Ezio Vasselli
We show that the Aharonov-Bohm effect finds a natural description in the setting of QFT on curved spacetimes in terms of superselection sectors of local observables. The extension…

Detlev Buchholz, Fabio Ciolli, Giuseppe Ruzzi +1
A recent idea, put forward by Mund, Rehren and Schroer, is discussed; it suggests that in gauge quantum field theory one can replace the point-localized gauge fields by string-loca…
