动力学重叠费米子观测量的拓扑求和

Topological Summation of Observables Measured with Dynamical Overlap Fermions

Wolfgang Bietenholz, Ivan Hip

摘要:

轻动力学重叠费米子的HMC历史往往停留在一个固定的拓扑扇区的许多轨迹,使不同的部门没有适当的采样。因此,对在不同部门测量的可观测量进行适当的汇总是一项重大挑战。我们探讨这个问题的几种技术,基于数据的手征凝聚体和(模拟)的π介子质量的2味Schwinger模型与动态的π-超立方体费米子。

英文摘要:

HMC histories for light dynamical overlap fermions tend to stay in a fixed topological sector for many trajectories, so that the different sectors are not sampled properly. Therefore the suitable summation of observables, which have been measured in separate sectors, is a major challenge. We explore several techniques for this issue, based on data for the chiral condensate and the (analogue of the) pion mass in the 2-flavour Schwinger model with dynamical overlap-hypercube fermions.
