The 1+1 Dimensional Abelian Higgs Model Revisited: Non-perturbative   Dynamics in the Physical Sector
  In this paper the two dimensional Abelian Higgs model is revisited. We show that in the physical sector, this model describes the coupling of the electric field to the radial part, in field space, of the complex scalar field.
