标题： Topological lumps and Dirac zero modes in SU(3) lattice gauge theory on the torus

摘要： 我们计算了在4维环面上具有拓扑电荷1的冻结SU(3)规范构型的格点狄拉克算子的本征模。 我们发现零模对施加在狄拉克算子上的边界条件有强烈的依赖性。 由本征模观察到的团块在改变边界条件时常常会改变位置，而团块的局部手性保持不变。 我们的结果表明，电荷1构型的零模可以与多个物体耦合。 我们探讨了这些物体是否可能是分数电荷的团块。 显示英文摘要

摘要： We compute eigenmodes of the lattice Dirac operator for quenched SU(3) gauge configurations on the 4-torus with topological charge 1. We find a strong dependence of the zero modes on the boundary conditions which we impose for the Dirac operator. The lumps seen by the eigenmodes often change their position when changing the boundary conditions, while the local chirality of the lumps remains the same. Our results show that the zero mode of a charge 1 configuration can couple to more than one object. We address the question whether these objects could be fractionally charged lumps.
