Monopoles and chiral-symmetry breaking in three-dimensional lattice QED

The chiral-symmetry order parameter {l angle}{bar {chi}}{chi}{r angle} and the monopole density {rho}{sub {ital m}} are calculated for lattice QED in 2+1 dimensions for zero and two fermion flavors. A comparison of the results for the compact and the noncompact lattice action yields a strong correla...

Zusammenfassung:	The chiral-symmetry order parameter {l angle}{bar {chi}}{chi}{r angle} and the monopole density {rho}{sub {ital m}} are calculated for lattice QED in 2+1 dimensions for zero and two fermion flavors. A comparison of the results for the compact and the noncompact lattice action yields a strong correlation between {l angle}{bar {chi}}{chi}{r angle} and {rho}{sub {ital m}} being essentially independent of the type of lattice action. This is interpreted as evidence that monopole condensation drives chiral-symmetry breaking in three-dimensional lattice QED.
