Ginsparg-Wilson方程的新解

New solutions to the Ginsparg-Wilson equation

Nigel Cundy

摘要:

重叠算子是一类具有精确手征对称性的Dirac算子中最简单的。我演示了如何一般类的手征狄拉克运营商可以构建,表明他们没有费米子倍增器,他们都是指数本地,并测试我的结论数字的几个例子。然而,由于这些算子比重叠算子更昂贵,因此它们不太可能在实际模拟中有用。

英文摘要:

The overlap operator is just the simplest of a class of Dirac operators with an exact chiral symmetry. I demonstrate how a general class of chiral Dirac operators can be constructed, show that they have no fermion doublers and that they are all exponentially local, and test my conclusions numerically for a few examples. However, since these operators are more expensive than the overlap operator, it is unlikely that they will be useful in practical simulations.
