Abstract
For the non-compact abelian lattice Higgs model in Landau gauge Kennedy and King (Princeton preprint, 1985) showed that the two point function\(\langle \phi (x)\bar \phi (y)\rangle\) does not decay in the Higgs phase. We generalize their methods to show that for the same range of parameters there are states parametrized by an angle θ∈[0, 2π) such that\(\langle \phi (x)\rangle _{Landau}^\theta = e^{i\theta } \langle \phi (x)\rangle _{Landau}^{\theta = 0}\) and\(\langle \phi (x)\rangle _{Landau}^{\theta = 0} > 0\).
