Generalized gauge-invariant regularization of the Schwinger model.
The Schwinger model is studied with a new one-parameter class of gauge invariant regularizations that generalizes the usual point-splitting or Fujikawa schemes. The spectrum is found to be qualitatively unchanged, except for a limiting value of the regularizing parameter, where free fermions appear in the spectrum.
متن کاملGauge Invariant Formulation and Bosonisation of the Schwinger Model
The functional integral of the massless Schwinger model in (1 + 1) dimensions is reduced to an integral in terms of local gauge invariant quantities. It turns out that this approach leads to a natural bosonisation scheme, yielding, in particular the famous “bosonisation rule” and giving some deeper insight into the nature of the bosonisation phenomenon. As an application, the chiral anomaly is ...
متن کاملGauge Invariant Variational Approach with Fermions: the Schwinger Model
We extend the gauge invariant variational approach of [1] to theories with fermions. As the simplest example we consider the massless Schwinger model in 1+1 dimensions. We show that in this solvable model the simple variational calculation gives exact results.

متن کاملLattice Regularization of the Chiral Schwinger Model
We analyze the chiral Schwinger model on an infinite lattice using the continuum definition of the fermion determinant and a linear interpolation of the lattice gauge fields. For non-compact and Wilson formulation of the gauge field action it is proven that the effective lattice model is Osterwalder-Schrader positive, which is a sufficient condition for the reconstruction of a physical Hilbert ...
متن کاملInvariant Regularization of Supersymmetric Chiral Gauge Theory
We formulate a manifestly supersymmetric gauge covariant regularization of supersymmetric chiral gauge theories. In our scheme, the effective action in the superfield background field method above one-loop is always supersymmetric and gauge invariant. The gauge anomaly has a covariant form and can emerge only in one-loop diagrams with all the external lines being the background gauge superfield...
