Chiral condensate in the quenched Schwinger model

TL;DR

This paper numerically investigates the quenched Schwinger model on the lattice, revealing that the chiral condensate diverges, which has implications for understanding chiral symmetry breaking in this model.

Contribution

It provides the first numerical evidence of a divergent chiral condensate in the quenched Schwinger model using the overlap Dirac operator.

Findings

Chiral condensate diverges in the quenched Schwinger model

Overlap Dirac operator effectively probes chiral properties

Results impact understanding of chiral symmetry in low-dimensional gauge theories

Abstract

A numerical investigation of the quenched Schwinger model on the lattice using the overlap Dirac operator points to a divergent chiral condensate.
