the Schwinger model regularization and gauge invariance Mathematical Physics
2012/6/21
The point-splitting computation of the gauge invariant Hamiltonian for the Schwinger model on the circle in a positive energy representation is presented.
A note on the vector Schwinger Model with the photon mass term: Gauge invariant reformulation, operator solution and path integral formulation
vector Schwinger Model photon mass term
