利用交错费米子和Lanczos算法计算了格点上的手征凝聚体{l_angle}{bar {chi}}{chi}{r_angle}。四个规范场被认为是：淬火的非阿贝尔场，阿贝尔投影场，和光子场进一步分解的阿贝尔场。阿贝尔投影在极大阿贝尔规范和Polyakov规范中进行。结果表明，在SU（2）和SU（3）色下，极大阿贝尔规范中的单极子在很大程度上再现了完全非阿贝尔理论的手征凝聚值。美国物理学会（American Physical Society）
Calculations of the chiral condensate {l_angle}{bar {chi}}{chi}{r_angle} on the lattice using staggered fermions and the Lanczos algorithm are presented. Four gauge fields are considered: the quenched non-Abelian field, an Abelian projected field, and monopole and photon fields further decomposed from the Abelian field. Abelian projection is performed in the maximal Abelian gauge and in the Polyakov gauge. The results show that monopoles in the maximal Abelian gauge largely reproduce the chiral condensate values of the full non-Abelian theory, in both SU(2) and SU(3) color. {copyright} {ital 1996 The American Physical Society.}
