On the vacuum structure of the Schwinger model
Tóm tắt
We discuss the generators σ of the vacuum structure of the Schwinger model. In the Lowenstein-Swieca gauge, we identify these operators with intertwining operators between different charge sectors of a free, massless spinor field ψ and use them as approximations for new operators σ∞ on an enlarged ψ Fock space. The σ∞'s generate states which are vacua with respect to the ψ Hamiltonian and their construction shows the connection with boundary conditions widely discussed in non-Abelian gauge theories.
