Quantum delocalization of the electric charge
Detlev Buchholz, Sergio Doplicher, Giovanni Morchio +2
The classical Maxwell-Dirac and Maxwell-Klein-Gordon theories admit solutions of the field equations where the corresponding electric current vanishes in the causal complement of s…
Superselection Theory for Subsystems
Roberto Conti, Sergio Doplicher, John E. Roberts
An inclusion of observable nets satisfying duality induces an inclusion of canonical field nets. Any Bose net intermediate between the observable net and the field net and satisfyi…
An Algebraic Duality Theory for Multiplicative Unitaries
S. Doplicher, C. Pinzari, J. E. Roberts
Multiplicative Unitaries are described in terms of a pair of commuting shifts of relative depth two. They can be generated from ambidextrous Hilbert spaces in a tensor C*-category.…
