A C*-algebra containing the CCR and CAR algebras as its subalgebras and naturally described as the semidirect product of these algebras is discussed. A particular example of this structure is considered as a model for the algebra of asymptotic fields in quantum electrodynamics in which Gauss’ law is respected. The appearance in this algebra of a phase variable related to electromagnetic potential leads to the universal charge quantization. Translationally covariant representations of this… 
This is the first of two papers on the superselection sectors of the conformal model in the title, in a time zero formulation. A classification of the sectors of the net of observables as
Massless Asymptotic Fields and Haag–Ruelle Theory

Infrared Finite Scattering Theory in Quantum Field Theory and Quantum Gravity

Spacelike Localization of Long-Range Fields in a Model of Asymptotic Electrodynamics
A previously proposed algebra of asymptotic fields in quantum electrodynamics is formulated as a net of algebras localized in regions which in general have unbounded spacelike extension.

Rigorous construction and Hadamard property of the Unruh state in Schwarzschild spacetime

Group algebras and crossed products have always played an important role in the theory of C*-algebras, and there has also been considerable interest in various twisted analogues, where the
Asymptotic algebra for charged particles and radiation
A C*‐algebra of asymptotic fields which properly describes the infrared structure in quantum electrodynamics is proposed. The algebra is generated by the null asymptotic of electromagnetic field and
Physical states in quantum electrodynamics
Because of difficulties with the Gupta-Bleuler subsidiary condition in the charged sectors, an alternative scheme for identifying physical states in the indefinite-metric space I of quantum
The physical state space of quantum electrodynamics
Starting from the fact that electrically charged particles are massive, we derive a criterion which characterizes the state space of quantum electrodynamics. This criterion clarifies the special role
Quasi-free states of the C.C.R.—Algebra and Bogoliubov transformations
We give a complete characterization of quasi-free states (generalized free states) of the C.C.R. algebra. We prove that the pure quasi-free states areall Fock states and that any two Fock states are
The smallestC*-algebra for canonical commutations relations
We consider theC*-algebras which contain the Weyl operators when the symplectic form which defines the C.C.R. is possibly degenerate. We prove that the C.C.R. are all obtained as a quotient of a
Asymptotic Structure of Space-Time
Many physical theories have the feature that one can distinguish within the theory a certain class of models which one regards as representing “isolated systems”. In Newtonian gravitation, to take
