摘要： 我们报告了在格点QCD模拟中使用重叠-狄拉克费米子算符的进展。我们研究了Borici基于Lanczos的方法以及各种有理逼近，以计算重叠-狄拉克算符中的跃迁函数。QCD模拟是在β=5.85，晶格体积为8**3*32下进行的。 显示英文摘要

摘要： We report on our progress in using the overlap-Dirac fermion operator in simulations of lattice QCD. We have investigated the Lanczos based method of Borici, as well as various rational approximations, to calculate the step function in the overlap-Dirac operator. The QCD simulations were performed at beta = 5.85 with a lattice volume of 8**3*32.
