摘要
本文把纯规范场的严格基态和费米场的变分真空态结合起来,研究格点QCD中2+1维SU(2)群带费米子的真空结构,计算费米子真空凝聚<ψψ>,其结果有较好的标度行为.
By incorporating the exact ground state of pure gauge theory and the variational fermion vacuum state, the vacuum structure of 2+1 dimensional SU(2) LGT with fermions is studied. We calculate the fermion condensate 〈(?)〉, and obtain a good scaling behavior.
