摘要
We investigate a recently proposed parity-invariant model of two-dimensional superconductivity. The model consists of two-species of fermions coupled with opposite sign to an abelian gauge field and is closely related to QED3. The first part of the paper is devoted to a detailed analysis of the relevant properties of QED3. In particular we study the dynamical generation of a parity-conserving fermion mass and the finite-temperature symmetry restoration transition. We show how the parity-invariant model arises as an effective long-wavelength theory of the dynamics of holes in a two-dimensional quantum antiferromagnet. The model exhibits type-II superconductivity without parity or time-reversal symmetry violation, a high value of 2DELTA/k(B)T(c), flux quantization with quantum hc/2e and a two-dimensional Meissner effect. We discuss the possible relevance of this model to the high-T(c) superconductors.
