摘要：
We study the critical indices of a high-Tc superconductor near its transition temperature Tc by assuming, phenomenologically, that superconductivity arises from a Bose-Einstein condensation of charged bosons (holons) in a resonating-valence-bond vacuum in 2+ dimensions. A self-consistent version of the static random-phase approximation leads to a quasiparticle spectrum (k)=Ak, with =1.766.. AE © 1990 The American Physical Society.
