Charges in light cones and quenched infrared radiation
Detlev Buchholz, Fabio Ciolli, Giuseppe Ruzzi +1
The creation of electrically charged states and the resulting electromagnetic fields are considered in space-time regions in which such experiments can actually be carried out, nam…
Where charged sectors are localizable: a viewpoint from covariant cohomology
Fabio Ciolli, Giuseppe Ruzzi, Ezio Vasselli
Given a Haag-Kastler net on a globally hyperbolic spacetime, one can consider a family of regions where quantum charges are supposed to be localized. Assuming that the net fulfils…
Gauss's law, the manifestations of gauge fields, and their impact on local observables
Detlev Buchholz, Fabio Ciolli, Giuseppe Ruzzi +1
Within the framework of the universal algebra of the electromagnetic field, the impact of globally neutral configurations of external charges on the field is analyzed. External cha…
The universal algebra of the electromagnetic field III. Static charges and emergence of gauge fields
Detlev Buchholz, Fabio Ciolli, Giuseppe Ruzzi +1
A universal C*-algebra of gauge invariant operators is presented, describing the electromagnetic field as well as operations creating pairs of static electric charges having opposi…
Relative entropy and curved spacetimes
Fabio Ciolli, Roberto Longo, Alessio Ranallo +1
Given any half-sided modular inclusion of standard subspaces, we show that the entropy function associated with the decreasing one-parameter family of translated standard subspaces…
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…
