Schwinger model on a finite-element lattice

- Summary
- Metrics

Abstract

The mass gap in the Schwinger model is calculated directly using a method which involves expansion in the lattice spacing. On the lattice the mass in the model is given by ..mu../sup 2/ = e/sup 2//M sin(..pi../M), where M is the number of spatial lattice sites. Current correlation functions and matrix elements are also examined.
