Abstract
The confinement of matter fields is studied in the compact (2+1)-dimensional QED theory of high-Tc superconductors. It is found that the monopole configurations do not affect the propagator of gauge potential aμ. This then leads to the findings that chiral symmetry breaking and confinement take place simultaneously in the antiferromagnetic state and that neither monopole effect nor Anderson-Higgs mechanism can cause confinement in the d-wave superconducting state. The physical implications of these field theoretic results are also discussed.
