畴壁费米子在Schroedinger泛函中的表述

A formulation of domain wall fermions in the Schroedinger functional

Shinji Takeda

摘要:

我们提出了一个制定的域壁费米子在薛定谔功能以下的普遍性参数Lüscher。为了检查是否制定工程,我们研究的自由畴壁费米子运营商的最低本征模。我们确认,该理论属于一个正确的普遍性类,本征向量是本地化的第五维的边界附近。我们还研究了四维有效算符的手征对称性破缺结构。我们观察到,体积手征对称性破缺消失了一个大的第五维尺寸,而起源于边界效应的破缺持续存在,并exponetially衰减远离时间边界。

英文摘要:

We present a formulation of domain wall fermions in the Schroedinger functional by following the universality argument given by Lüscher. To check whether the formulation works, we examine the lowest eigenmode of the free domain wall fermion operator. We confirm that the theory belongs to a correct universality class and that the eigenvector is localized near the boundaries of the fifth dimension. We also investigate the chiral symmetry breaking structure of the four dimentional effective operator. We observe that the bulk chiral symmetry breaking disappears for a large fifth dimensional size, while the breaking originated by the boundary effects persists and exponetially decays away from the time boundaries.
