Gauge Invariance and Symmetry Breaking by Topology and Energy Gap
Carlo Heissenberg, Franco Strocchi
For the description of observables and states of a quantum system, it may be convenient to use a canonical Weyl algebra of which only a subalgebra , with a non-trivial…
Dynamics of Dollard asymptotic variables. Asymptotic fields in Coulomb scattering
G. Morchio, F. Strocchi
Generalizing Dollard's strategy, we investigate the structure of the scattering theory associated to any large time reference dynamics allowing for the existence of Møller…
Localization and symmetries
G. Morchio, F. Strocchi
The violation of the Noether relation between symmetries and charges is reduced to the time dependence of the charge associated to a conserved current. For the U(1) gauge symmetry…
Mathematical structure of the temporal gauge
J. Loeffelholz, G. Morchio, F. Strocchi
The mathematical structure of the temporal gauge of QED is critically examined in both the alternative formulations characterized by either positivity or regularity of the Weyl alg…
Ground state and functional integral representations of the CCR algebra with free evolution
J. Loeffelholz, G. Morchio, F. Strocchi
The problem of existence of ground state representations on the CCR algebra with free evolution are discussed and all the solutions are classified in terms of non regular or indefi…
Representations of the Heisenberg algebra on holomorphic functions and Krein structures
M. Mnatsakanova, G. Morchio, F. Strocchi +1
Representations of CCR algebras in spaces of entire functions are classified on the basis of isomorphisms between the Heisenberg CCR algebra A_H and star algebras of holomorphic op…
